I believe I have a late 1944 production HSc based upon serial #9256XX. The only marking is an eagle over "N" on the right trigger guard web which I believe means it is a commercial model. This was given to me by my father who was in France and Belgium during WWII. It came with a holster which I believe may have been original to the gun, but I can't be sure of that. My curiosity is with the holster, as there is an area on the flap that has been blackened for some reason. I have pictures on my phone, but don't know how to post them on this forum. If someone knows how to do that I could send them the photos from my phone. Thank you for any help.
