Ok guys and gals I have an old "Columbia" shotgun 12 gauge single shot and can't find any info on it. I know the gun is not worth a ton of money. I have search online and found more question's than answers and even taken it to a couple (8) gun dealers and nothing. I have been offered $100 all the way up to a even trade for for a used 40 S&W. I can not get rid of the gun it has family history. So if any one knows something about this gun please let me know. Here is what I do know. It was a "drug store" shotgun carried by a lot of different stores. Many people imported them in from ????????????? country. Most of them are 60-100 years old. Thanks in advance for your help.
