This is my Predom Lucznik WZ 1976 air pistol. It was manufactured by Zaklady Metalowe Predom-Lucznik in Radom, Poland from at least 1972 to about 1980 it is a copy of the Walther LP53. The parts are interchangeable but the LP53 is a much more refined gun., Lucznik is a Polish gun factory, possibly the state firearms factory, or what we might call an arsenal. They make military weapons. In the 1970s and ’80s, they also made a curious single-shot pellet pistol that was a knock-off of the famous Walther LP53. The LP53 is most famous as the gun Sean Connery held for many publicity photos for James Bond films. Because they were filming in the UK, it was easier for the film’s media team to use an airgun than a firearm. , The Predom is a .177 caliber breakbarrel that cocks in a very strange way. The piston is located vertically in the pistol grip and, upon firing, springs upward. , https://youtu.be/_CLeg1hDwqM
