I inherited a Marlin model 1894 in cal. 25-20. The serial # seems to be 3370xx, but the first two numbers are poorly formed and hard to read. It shoots well, although my eyes don't work well enough any more to shoot a very tight group with open sights. The gun's exterior appears to be in excellent condition, except sometime in the past someone tried to remove the barrel with a pipe wrench or the like, leaving some scars around the base of the barrel. I will try to post some photos eventually. Can anyone tell me about that serial number? Any other comments of note?
