Soft shell HOLSTER made in pebble black grained leather and designed for the P27(t).
The markings are present on belt loop : Inspection mark (Ealge/WaA721) and a difficult to read RBNr. EZGJ with assembly date (1944).
This is a very nice classic end war HOLSTER for the Cz27 pistol.
The same HOLSTER is detailed in the book WW2 German MILITARY Holsters on page 404.
