Third and fourth from left are 1st pattern WWII, I believe made originally for the Chinese contract HPs. They are poor holsters (well made, poorly designed) that will let the pistol fall out if not buckled down. Far right is 2nd pattern WWII and work well. In the 80s a bunch of them made by ZL&T, unissued, came on the market, so while getting harder to find they aren't rare. Many, if not most, of the WWII, especially the unissued ones, have shrunk over time and are a very hard fit. Lots of tugging and pushing to get a pistol in.
