Opinion
Paul Eugene Corkrean was charged with possession of a machine gun in violation of Penal Code section 12220. 1 A jury was waived and he was tried by the court. The court found him guilty and placed him on three years probation. The question presented by his appeal is whether an element of the crime proscribed by section 12220 is knowledge that the weapon possessed is an automatic one. We hold that it is not.
Facts
Solano County Deputy Sheriff Hall, responding to a civil dispute on Jamison Canyon Road, observed appellant’s car parked in the driveway. In plain view on the passenger side floorboard of the car was an AR 15 automatic rifle. Appellant acknowledged that the weapon was his.
A weapons expert testified that the AR 15 is a semiautomatic rifle which can be converted to a fully automatic weapon by the exchange of certain of its parts with M-16 parts. The necessary exchange of parts had been made on appellant’s rifle. Appellant testified that he had recently rebuilt his weapon with parts he had purchased at a gun show. He stated that he had not had an opportunity to fire the weapon since making the changes and that it had been his belief that the weapon would fire only semiautomatically.

v.
Daniels
(1953)
Section 12220 provides in pertinent part that “[a]ny person . . . who within this state . . . possesses or knowingly transports any firearms of the kind commonly known as a machine gun, ... is guilty of a public offense . . . .” Pursuant to section 12200, the term “machine gun” includes any weapon that shoots automatically more than one shot, without manual reloading.

Williams
(1971)
In the case at hand we are concerned not with the narcotics possession law, but with the statute commonly known as the machine gun law. (§ 12200.) No argument is made that the Legislature could not validly punish innocent possession of a machine gun, nor does it appear that such an argument would prevail. The common law principle that there must be a union of act and wrongful intent, expressed in section 20, although basic, is not inviolable. (See

v.
Hernandez
(1964)
As indicated, the Machine Gun Law prohibits possessing or “knowingly” transporting a machine gun. The statute thus is distinguishable from the narcotics possession and transportation law (former Health & Saf. Code,
*39
§ 11500; see now Health & Saf. Code, §§ 11350, 11352) because the latter does not use the word “knowingly” with respect to any of its prohibited acts. (See
People
v.
Daniels, supra,
That the Daniels court correctly construed the Legislature’s intention in the machine gun law is suggested by a review of other provisions of The Dangerous Weapons’ Control Law (Pen. Code, pt. 4, tit. 2, §§ 12000-12601), of which the machine gun law is now a part. In addition to possession of a machine gun (§ 12220), other possessory offenses proscribed under The Dangerous Weapons’ Control Law include possession of specified dangerous weapons (blackjack, billy, nunchaku, sawed-off shotgun, metal knuckles, etc.) or specified ammunition (§ 12020, subd. (a)), possession of destructive devices (§ 12303), possession of fixed ammunition of a caliber greater than a .60 caliber (§ 12304), possession of handgun ammunition designed to penetrate metal (§ 12320), and possession of tear gas or a tear gas weapon (§ 12420). The Dangerous Weapons’ Control Law also prohibits the carrying of a loaded firearm in a public place. (§ 12031.)
A comparison of the terms of these statutes is instructive. The Dangerous Weapons’ Control Law, as initially enacted in 1953 (Stats. 1953, ch. 36, § 1, pp. 653-665), prohibited any possession of a machine gun (§ 12220) and any possession of specified dangerous weapons (§ 12020), but prohibited only knowingly possessing tear gas or a tear gas weapon (§ 12420). Through subsequent amendments, The Dangerous Weapons’ Control Law now additionally prohibits possessing or knowingly transporting specified fixed ammunition (§ 12304, added by Stats. 1967, ch. 1283, § 1, p. 3087), knowingly permitting another to carry a loaded weapon in one’s car (§ 12034, added by Stats. 1977, ch. 528, § 1, p. 1732), and knowingly possessing and knowingly transporting specified handgun ammunition (§§ 12320, 12321, added by Stats. 1982, ch. 949, § 3, p. 3439). The Legislature’s repeated selective use of the word “knowingly” throughout the Dangerous Weapons’ Control Law thus supports the Daniels court’s conclusion that, in the weapons field, the Legislature has consciously distinguished between possessory and other offenses requiring knowledge, and *40 possessory offenses punishable without regard to the defendant’s awareness of the character of the item possessed.
Furthermore, “[a] cardinal principle of statutory construction is that the Legislature is presumed to be aware of existing judicial practices and interpretations when it enacts a statute. [Citation.]”

Appellant argues that in 1927, when the machine gun law was first enacted (Stats. 1927, ch. 552, § 1, p. 938), gun technology was relatively
*41
simple, but with modern technology, expertise is needed to distinguish automatic weapons from legal rifles. He maintains, therefore, that to punish possession without proof of knowledge is unjust, and that, pursuant to
Baender
v.
Barnett
(1921)
Baender
v.
Barnett
is distinguishable because the knowledge there at issue was knowledge of possession itself, not knowledge of the character of the thing possessed. Moreover, as indicated, in the machine gun law and related provisions of The Dangerous Weapons’ Control Law, the Legislature has manifested its intention to dispense with knowledge of the character of the item possessed as an element of specified crimes.
