Hope you are enjoying your TC Hawken Heat. I bought mine new (in 45 cal), back in 1974. Can't recall the exact price but believe it was around $150 or a bit more. At the time alot of traditionalists cut them down saying they only had the one barrel wedge, coil mainspring, to short of a barrel, to fast of a rifling twist for ball, the adjustable sights, and about anything else they could come up with. Well after almost 50 years of having the TC 45 I can still hit alot of what alot of shooters can't hit with modern open sight smokeless rifles and the TC is still going strong. Shoot round ball loads through it mostly.
Back around the mid 80's I cut the finger loop or whatever its called off of the bottom of the trigger guard just behind the triggers as I never cared for its feel or looks. Blackened the brass with cold bluing and lightly rubbed it with steel wool and refinished the stock. I used some of Browells powered wood stains mixed with water to find a color I liked on the TC walnut (sort of a dark reddish hue) and refinished the stock with a wood finish called Arrow. It is similar in use as Tru-oil, but I had used it before and liked its looks better. Wears like iron. Still available last I knew online, bought a bottle several years ago. Bought my first bottle of it at a gunshow several years prior to using it on the TC from the developer and owner of the business at a gun show. Like the looks better of my refinished TC than in its original format.
Thee Ol TC's are great guns, may not be as original as Sams, but they are quality rifles and got alot of shooters into black powder rifle shooting. Back in the day the TC was of better quality than most of the rifles/kits made outside of the US and 'alot' cheaper than some of the more expensive muzzleloader Hawken styles like the old Green River rifle brand. Too bad TC was sold to Smith and Wesson who IMO ruined the original Warren Thompson developed rifles with the production of those ugly inliners and tried to develop modern centerfire style rifles to compete with present day rifle manufacturers. Have never regretted my TC Hawken buy in the summer of '74.
