Thanks this shotgun has the bayonnet mount in the the front I have the bayonnet also I see no military markings at all that I can see. It has the short 20" barrel with the heat shield over the top. On the top of the barrel it says Ithaca Model 37 Featherlight. Would it help you if i gave you the complete serial number I can? Also I have some pictures but I am new to this and don't know how to post to this site. Can you help me?
