I had a question asked of me about North Korean PG-7 rounds. I have no written data on any standard PG- HEAT round, but I do on this unusual Fragmentatiion round. There are no external markings on the round to identify it as North Korean. The external markings appear to have been not done in Korean so it could be exported without being traced. The only ID is taken from the markings on the internal base fuze. The round can be found painted either in dark green or gray, but both have a single red band on the body as shown. Markings on the warhead are, for example: "F-7 8-81". On the motor are: "NR-4 8-81-T". All markings are in black. Because of the gray paint on the first rounds encountered they were thought to be chemical, but it turned out that was not true and there was not a shaped-charge cone either. The warhead contains a two-piece phenolic type sleeve with round steel balls embedded in it. Each ball is about 5mm in diameter. The complete round weighs a little over 4 pounds and it contains about a 9 ounce charge of explosives inside the frag sleeve. There is no point initiating element in the warhead, just a simple impact base fuze. The fuze markings give in addition to the typical year and lot information, the Korean marking for "PG-7 Type", instead of a separate fuze designation. Fuze markings are stamped in black ink. I'll attach another post with drawings that give the round dimensions.
