Greetings from a 45 year Walther collector ( WWII vet ) in the USA. I recently located a black leather IWB holster marked for the Walther PP with the NATO part nr. 978-2247 dated 07/91. This holster is totally different from the brown leather one issued to the UDR to carry the cal.22 PP in the 60's. I have been told that this black holster was issued to low profile SAS personnel as an alternate to the BHP. I understand that the RAF issued Walther PP in cal 7.65mm, but these were not issued with holsters. The pistol designation was L47A1. Would this have been the same designator for the SAS issue? Any information about the RAF/SAS Walther PP and/or holster would be greatly appreciated.
