i have an old stevens double barrel 16g shotgun i got from my grmpa. Im looking to get ins coverage on all my firearms, so the insurance is asking for #'s. I cant find any on it at all. On one side it has the dog stamped and on the other it just says stevens. Anyone know where it would be???? Not on barrel or anything. Me and my dad had it reblued about 10-12 years ago, could that hav covered it up or in some way degraded the #'s???? Thanks everyone.
