This is an early post-WWII Czechoslovakian Model 23 submachine as reactivated by the Joe Petty company prior to the 1986 import ban. This model was developed shortly after WWII and was used by the Czech Army until they were overtaken by Russia. It as comprised of mostly stamped sheet metal type parts that are welded together with a heavy machined telescoping bolt and barrel. They came in two different version: the Model 25 with a simple folding wire stock and this example, the Model 23 with the fixed wooden stock. They are fitted with a red bakelite forestock and pistol grip panels with the slap sided wooden stock. This example was deactivated by having the front end of the receiver tube cut off and was reactivated by welding the original front end back on to the receiver and registering it with the BATF by the Joe Petty Company, NC. It also has a new manufactured barrel still in the white. The rear of the receiver is stamped: "JOE PETTY/STANLEY NC/JP01/JP8873". It has an all black painted exterior finish and comes with one original 30 round Czech stick magazine.
