Does anyone know if there are any kits out there for the English style halfstock smoothbores. Most of the smoothbore kits I have found are Trade Guns, and Barn Guns. I would like something that is well balanced not excessively long and around 20 Gauge. I have put together a few percussion kits in the past and am getting interested in flint smoothbores. Also a lot of stocks I have seen have a lot of drop, which I dont favor. If there aren't any kits, which there probably aren't, is there any good literature to get on building an Engish style halfstock. Any information appreciated.
