I don't think it's too difficult to capture the nuances that make or break a Hawken rifle, if the builder studies and pays close attention to the details. But one of the common fails I see in builds is the use of castings offered in today's market. Some of these are salvageable by filing, etc. and make suitable parts. One such part is the Hawken butt plate. Many castings do not have the heel spur that was common on the Hawkens' rifles. Today's offerings lack the extended heel and feature a flat uninteresting heel. This might be more comfortable to shoot, especially prone, but to my eye, is BUTT UGLY...sorry for the pun.
TOW's Jim Bridger butt plate approaches the correct shape, and can be improved with judicious filing. Also, Don Stith's buttplates are excellent too. I post a couple of pictures here of one as an example...
