Have built many LRs from blanks, but just ordered an "Early Lancaster" kit from Chambers. Have assembled and sold a finished rifle from this same kit 2 yrs. ago and it was a pleasure working on it. The lock is probably the best on the market, the bbl is by Rice {tops} and the brass components are investment cast from soft yellow brass. The stock was profiled very close to the finished size, but left ample wood for carving and moldings. The various inlets are close, but require some chiseling, mainly in the corners. Inletting the breech in reference to the inletted lock pan and "White Lightning" touch hole liner location isn't at all difficult but probably is the most involved operation of the assembly. This kit isn't low cost {$900 and up} but all the components are first rate and could result in a superb LR, depending on the assembler's skill. Outside of the "factory sand and finish kits"{ some of which are good}, the Chambers kits are the next step if cost isn't a deterrent....Fred
