I have the opertunity to become the new owner of a H&R 16 Ga. single shot break action that only has the numbers 2818 stamped in the receiver and barrel. I have read many post's all over the web talking about the letter "A" or "I" in the serial number. But this one has no other number or letter's there or even a model number of any kind on it. I will try to get a few photo's on here to help. Any ideas what year it might have been made ? I really don't care about its "value" just want to know if I should restore it or go ahead and make it into my new sawed-off bed side arm or not. It is in rough shape but looks to still be usable, will know more after a cleaning off of the years of barn dust on it.
