Sheepherder,
The P38 holster you posted the link to is an original wartime holster. Made by "jwa", Moritz Stecher in 1944. This is what is know as a Russian Capture holster. A large number of these unissued holsters were imported from Russia/Ukraine back in 1999.
$30 for that holster is a bargain! Whoever got it?
This style of holster began to appear in 1943, and eventually was to replace the hard shell style. It's know as a "break-away" holster. This is because when you pull the closure strap up, the flap lifts, and the inner "break away" flap opens up, and allows the user to easily remove the pistol. No lift strap needed. This holster was much easier and cheaper to produce.
Spanner,
Your holster is also original. Appears to be a "jhg" 1944 date. This is for GECO. Proof should be WaA41.
