The original piece itself is perspex, from the windshield of a shot-down US helo in Korea.

Made into grip panels (with custom screws) by the Auld Soldier's maintenance tech to replace the grips on the 1942-dated Tula-built TT33 pistol that the Auld Soldier captured from it's non-functioning previous owner of Chinese heritage. The grip panels needed replacing because they had been holed (without damaging the frame) by a .45 caliber bullet from the Auld Soldier's M1917 revolver during a confused fight in the woods outside of Sinju, North Korea.
Here's where Sinju is located. On the river between North Korea and China. This was the Eighth Army Front line at the time. Just north of Seoul.
Anybody has a spare firing pin and spring, firing pin retaining pin, and the hammer stop, I'm in the market. When the Auld Soldier put the piece on the plaque, he removed those parts and the two of us spent hours over the years trying to find them, obviously without success.

Worse comes to worse, I'll buy one of the ahistorical new imports and strip the parts I need from that.
WIth the known facts and personal connection is is REALLY, REALLY GREAT!
Dad was with the United Nations Partisan Forces Korea (UNPFK). His particular group called themselves the Yangtze River Pirates and operated from the islands off the northwest coast of Korea near the mouth of the Yalu (and Sinju, which is just upriver from the coast).
Dad was doing SF stuff, working with locals who had been fighting the communists on their own. He was SF before it was popular.
