Thanx much for the info., I'll see what I can get done. Until then anyone willing to look I have photos I could email. Yes I'm sure both bbl. are smooth. After a couple hours of brushing & patching, using a bore light about 3' long I can see no sign that any rifling had ever been in either bbl. This gun is perplexing, in some ways it's tooooo plain to have this amount of silver work. If you look at it straight on it looks like any other American made half stock, a very trim gun with beautiful lines. There is no engraving on either lock, no names on locks or bbl.'s. The but & toe plate are brass, the trigger guard is brass and silver. Between the toe & trigger guard there are 3 inlays. On top of the wrist it has silver from the breach to the comb. The cheek piece has a really cool 2 1/4" x 1 1/2"silver oval with engraved eagle. On the forend it has 2 wedges both have silver. The forend cap is silver and scroll silver inlay down the the under side of forend and 2 silver ram rod thimbles. It has a fixed rear sight & thin silver front sight. Both bbl.'s start out as octagon 3/8" across the flat & turn round about 12" from breach. Barrels are 40 1/2" long 58 5/8" muzzle to heel. I almost forgot, it has a set trigger.
