Featherman: I have it's twin. Lovely little gun. Mine is bored Imp Cyl and Mod. I can actually hit things with it...occasionally. The stock is quite short for me, and not enough drop so the toe of the butt gives me bruises in the shoulder, even though it's a 28 gauge.
I realize it's a year afte this post. I have a Coin finished 28 Ga with modesst engraving. Forearm has a beautifully inlaid horn tip. It's a Wayne import. I managed to contact Mr Wayne a couple of years ago and described it to him and he thinks mine is an R 15. It does lack the obutrator disks. I wonder if this is common on the smaller gauges.
