Aftеr a jury trial, Criss Duncan was convicted of the following offenses: armed bank robbery, in violation of 18 U.S.C. § 2113(a) and (d); use of a firearm during and in relation to that bank robbery, in violation of 18 U.S.C. § 924(c); aiding and abetting the malicious damage by fire to a vehicle, in violation of 18 U.S.C. §§ 844(i) and 2; and possessing a firearm despite being a felon, in violation of 18 U.S.C. §§ 922(g)(1) and 924(a)(2). Mr. Duncan appeals his sentence. For the reasons set forth in the following opinion, while retaining jurisdiction, we order a limited remand of this case to the district court as required by
United States v. Paladino,

BACKGROUND
A. Facts
We shall set forth only those facts germаne to Mr. Duncan’s present challenge to his sentence. On May 27, 2003, he and his co-defendant Ralph Berkey, each armed with an assault-type rifle, robbed the National City Bank locаted in Leesburg, Indiana. At Mr. Duncan’s trial, Berkey testified that the firearms that they had used during the robbery had been modified to be fully automatic. R.126 at 25, 41-42. In addition, Larry Joe Ellis testified that, prior to the robbery, he had worked for Berkey to make several firearms fully automatic. Id. at 22-24. According to Ellis, after the robbery, Mr. Duncan and Berkey left Mr. Duncan’s Mazda truck on Ellis’ property, and Berkey tоld him to “[wjipe the fingerprints off the guns. Take care of them for me.” Id. at 22. Ellis found two fully automatic firearms in the truck, and he converted them back to semi-automatic.
*682 The presentence report prepared in Mr. Duncan’s case recommended, with respect to the charge of using a firearm during and in relation to the bank robbery, that the firearms used by Mr. Duncan аnd Ber-key be categorized as machine guns. 1 This classification had important consequences for Mr. Duncan: For violations of 18 U.S.C. § 924(c)(1)(A), the statutory minimum sentence for a semi-automаtic firearm is ten years, id. § 924(c)(l)(B)(i); the minimum for a machine gun is thirty years, id. § 924(e)(l)(B)(ii). 2 Moreover, this minimum prison term is “in addition to the punishment provided for” the underlying crime of violence, here the armed bank robbery. Id. § 924(c)(1)(A). Mr. Duncan maintained that no actual proof was established at trial that the firearms were in fact fully automatic.
B. District Court Proceedings
Over Mr. Duncan’s objection, the district court found that the testimony of Berkey and Ellis established, by a preponderance of the evidence, that the firearms used in the National City Bank robbery qualified as machine guns. Under the law prevailing at the time оf sentencing, this finding required the district court to sentence Mr. Duncan to at least thirty years in prison on the firearms count. See id. § 924(c)(l)(B)(ii); see also U.S.S.G. § 2K2.4 (the federal guidelines sentence for violations of § 924(c)(1) is the statutory minimum).
The guidelines sentencing range for Mr. Duncan’s remaining convictions was 97 to 121 months. The final guidelines range was 457 to 481 months. The district court imposed a sentence of 457 months’ imprisonment, stating:
In my thirty plus years as a federal judge, because of the mandatory thirty years for using a machinegun, this is without a doubt the longest sentence this Court has given for a bank robbery. A sentence at the low еnd of the range still places him in federal custody for almost forty years, and seems more than adequate.

DISCUSSION
A. Standard of Review
Mr. Duncan contends that his sentence violates his Sixth Amendment rights
*683
as interpreted by the Supreme Court in
United States v. Booker,
— U.S. —,
The plain error standard allows an appellate court to “correct an error that the defendant failed to raise below only whеn there was (1) error, (2) that is plain, and (3) that affects substantial rights.”
United States v. Henningsen,
B. Sentence
1.
With respect to Mr. Duncan’s contention that
Booker
and
Blakely
require the vaeation of his sentence because it is based on a mandatory minimum sentence, the Supreme Court’s decision in
Harris v. United States,
Contrary to Mr. Duncan’s submission, nothing in
Booker
or
Blakely
suggests that the Court reconsidered, much less overruled, its holding in
Harris. See United States v. Lee,
Moreover, even if the logic and spirit of those decisions could be interpreted to have еroded the Court’s previous rationale for permitting mandatory
*684
minimum sentences based on judicial fact-finding, it certainly is not our role as an intermediate appellate cоurt to overrule-a decision of the Supreme Court or even to anticipate such an overruling by the Court.
See Roper v.
Simmons, — U.S. —, —,
2.
Mr. Duncan’s sentence nevertheless requires our intervention. The district court imposed his sentence prior to
Booker
and, understandably, believed itself bound by the federal sentencing guidelines. Our cases hold that, in light of
Booker,
such a misapprehension can amount to plain error.
See, e.g., United States v. Castillo,
If Mr. Duncan were to bе resentenced, the district court still would have no discretion to sentence him on the firearm offense to less than the statutory thirty-year minimum. However, this sentence runs consecutively tо the sentence imposed because of Mr. Duncan’s other offenses. See 18 U.S.C. § 924(c)(1)(B). This latter component of his sentence is not tied to a statutory minimum. Thus, Booker would afford the district court some additional discretion with respect to Mr. Duncan’s total punishment. The district court chose a sentence at the lowest end of the applicable guidelines range and exprеssed the concern that,
[i]n my thirty plus years as a federal judge, because of the mandatory thirty years for using a machinegun, this is without a doubt the longest sentence this Court has given for a bank robbery. A sentence at the low end of the range still places him in federal custody for almost forty years, and seems more than adequate.
R.133 at 14. This statement suggests that the district court, even though still bound by the statutory minimum, may well have imposed a lighter total sentence if it had not believed that it was bound by the sentencing guidelines to impose the sentence that it did impose. Wе cannot know this, however. To enable us to complete our plain error analysis, a limited remand to the district court, in accordance with the procedure outlined in this сourt’s decision in
Paladino,
*685 Conclusion
Accordingly, while retaining jurisdiction, we remand this case to the district court for proceedings consistent with this opinion.
It Is So OjrdeRed.
Notes
. “Machine gun” is defined under 18 U.S.C. § 921(23), by reference to 26 U.S.C. § 5845(b), as “аny weapon that shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.”
. Title 18 section 924(c)(1) provides in.part:
(A) Exсept to the extent that a greater minimum sentence is otherwise provided by this subsection or by any other provision of law, any person who, during and in relation to any crime of violеnce ... uses or carries a firearm, or who, in furtherance of any such crime, possess a firearm, shall, in addition to the punishment provided for such crime of violence ...—
(i)be sentеnced to a term of imprisonment of not less than 5 years;
(ii) if the firearm is brandished, be sentenced to a term of imprisonment of not less than 7 years; and
(iii) if the firearm is discharged, be sentenced to a term of imprisonment of not less than 10 years.
(B) If the firearm possessed by a person convicted of a violation of this subsection—
(i) is a short-barreled rifle, short-barreled shоtgun, or semiautomatic assault weapon, the person shall be sentenced to a term of imprisonment of not less than 10 years; or
(ii) is a machinegun or a destructive device, оr is equipped with a firearm silencer or firearm muffler, the person shall be sentenced to a term of imprisonment of not less than 30 years.
18 U.S.C. § 924(c)(l)(A)-(B).
. The other courts of appeals to have addressed this issue have concluded that
Booker
does not apply to statutory mandatory minimum sentences.
