I have used three of TOW's Lancaster precarved stocks, the one made for a 44" barrel, and they all turned out very well. But all three were over inletted for the barrel in the midway area of the fore arm, requireing glass bedding to close the empty space under that portion of the barrel. If pulled up tight to the barrel, the RR groove would curve noticably, following the swamp of the barrel. As a side note. The L&R Queen Ann round faced lock can be fitted their lock inlet. I have done it twice at any rate, but unfortunately, the Chambers version cannot be fitted to their inlet. Their frontal cut is too wide for the Chambers. I would also add that the TOW maple stocks are just a tad on the soft side. Not real bad, but softesh.
