If you ask John, he has very detailed information on the pre WWI NM rifles .. probably he would share it with you?

Rick, that SA 1919 NM rifle would be very great to have! If you ever decide to part, I'd love to put it right next to the "unwanted" RIA 1919 NM. I think they would make a great couple! Of course I wouldn't mind to have the 1916 NM rifle too, just to make sure that I somewhen have every year.

And the other Rick, the Thread Starter, please also post pictures of your 1920 NM rifle!
