Scarce Theuermann HOLSTER designed for the P38, made in high quality black leather.
The 2 drop straps are internal and there is a big large belt loop. The mag pouch is inside and provides place for 2 spare magazines which is quite unusual !
The classical Theueurmann patent is deeply inscribed on this belt loop.
Not so many holsters of this type have survived (probably only 3-4 ?) as they were never produced in large scale.
Another sample is pictured in the book about WW2 German Military Holsters on page 115 (from John James collection).
