I have a canadian holster that is very similar. It has the sewn on shoulder strap and belt loop and overall the profile is the same. However, my buckle is closed and the holster has a snap button located on the flap further to the right instead of the snap on the strap. Also no liner. I believe mine is marked MS&ULT 1942 (a little hard to read). It is definately a flare gun holster and fits my 25mm Mark IV Very Pistol quite nicely (US manufacture marked A.H.Fox Gun Co Phila.Pa.U.S.A.)
