Some Mil Pats were used by the forces and appropriately stamped examples can be seen on the vintage BSA Airgun forum. I have an early pre WW1 Ordinary Pattern that has been stamped with the WD 'crow's foot' and fitted with the butt from an SMLE (not my SMLE Lincoln, which was a later conversion). The story I was told was it was part of a batch used by cadets but I was never able to substantiate this. I suspect BSAs would have been used by cadets as they were so useful and accurate - we just need to unearth some concrete proof of this.

Currently looking for Baikal Makarov pistols with the following prefixes to the serial number: 98, T01, T09, T21, T22
Prefer boxed or cased but will consider loose examples too.
