I am working on a Chamber's Early York kit. I have never seen the real McCoy, and have been studying photos of the York rifles in the library. Immediately behind the breach end of the barrel, the stocks seem to all be contoured down to meet the top two diagonal flats, along with the top flat and tang. From the pictures, I cannot see how to do this and make the stock side panels look right. (Especially the left one.) Can anyone show closeup photos of this area on a rifle made this way? I have several books on recreating the longrifle, and none zero in on this detail. Thanks!
