I have a Mosin that I love to shoot ,because it is very accurate I did not know anything about Mosins and described the rifle on this forum and asked what model it is , and Vic retorted with a very lengthy reply ," 28/30" . Well, after being directed to the Mosin site, I am quite a bit less stupid now. Anyway, I have acquired three more 28/30's this year by beginner's luck and not skill. My son finally dug the Mosin he has had in his closet for twenty years out and gave it to me. It is a 1936 28/30, no import marks. Receiver, bolt and stock match. There is "SYS" deeply impressed into the right hand finger groove. It is missing the mouse trap spring, and if anyone can inform me where I can acquire one, it will be much appreciated. How does one post pictures on this new format?
