This is a scarce example of a Vietnam era Chi-Chom Type 50 or K-50 submachine gun. These were produced in country in the early days of Vietnam before the infusion of the thousands of the SKS/AK-47s from both China and Russian. They are a combination of the WWII PPSH-41 and PPS-43 Russian submachine guns that used the lower trigger housing group from the PPS-43 and the top receiver portion from the Russian PPSH-41. They had a shortened perforated barrel shroud with an expose front barrel section. The example has an AK47 type front sight base and post that is pinned on to the front of the barrel with the standard two position flip rear sight from the PPSH-41. It used a telescoping wire stock copied from the French MAT-49 submachine guns. It did not have a handguard of any type but used a pistol grip similar to the AK47. It was a simple blow-back type action that fired the Russian 7.62 X 25 mm pistol cartridge using a Russian PPS-43 type magazine. The top of the receiver is stamped with assembly number "2475 over 356811" with the last three digits of the assembly "475" stamped on the left side of the lower trigger housing grip and pistol grip. The weapon has been rendered unserviceable by welding a plug in the chamber of the barrel and also the underside of the barrel trunnion has been welded to the upper and lower receiver/trigger housing groups. It comes with one 30 round magazine and is currently registered as an unserviceable C&R weapon.

Very good with a mostly dark brown patina finish showing rough forging/stamping marks on the sides overall. The markings are clear. The pistol grip is in good condition. A very scarce and seldom registered Vietnam era Chi-Com Type 50 SMG.
