Luger Holster Berlin - Please Comment

[Lugermeister]

I purchased the 1937 marked, S/42 Luger shown in the first picture. It came with this holster. It is marked Berlin and has the same 9207 number matching to the gun.

What can you tell me about this holster? I was told that it was designed to hold a regulation Luger and/or an Artillery Luger.

Thanks for educating me on my first Luger and holster.
