I recently ran across a strange single shot 12ga "Semi-Hammerless" shotgun made by the American Arms Co. in Boston. I was referred here by some folks from gunboards and even though its not a double they said you folks know lots of info about this kinda stuff! I posted a link to my post with pictures on gunboards.

I'd like to know more info about this shotgun and also if the pattern on the barrel can be restored as the rest of the gun is in good shape and the wood is a fancy looking grade in great shape.

Thanks!
