Picked up a new to me uderhammer this weekend at local gunshow!

I have not gotten to shoot it, but it looks  like the underhammer action that Pecatonica sells, with a heavy, short .45 rb barrel on it, 24". Barrel looks mint, will need to make a ramrod for it, got it for a steal,$90! It has a nice black walnut stock and forearm also!

Is it a Numrich/Hopkins&Allen? If so, be aware that it probably takes an oddball nipple instead of the old standard 1/4-28. On top of that they come in two different lengths of the threaded part to account for differences in barrel wall thickness. TOW has what you need so it isn't a  problem, just something to be aware of.

God is with you Sam, keep us posted on how it shoots.
