Well TC parts and CVA parts are drying up...,
On the other hand CVA used rifles tend to go for a lot less than the TC rifles..., though stick to caplock in CVA unless you want to tinker a lot with the CVA flinter (imho). You can, luckily, replace the flintlock on either by getting an after market lock by L&R..., which must be fitted. {(iirc) you can replace the caplock lock too.}
Uncommon and sought-after, and no longer in production....TC Seneca and Cherokee rifles...especially if you get two barrels; one for deer and one for small game. They were small and light so were/are a lot of fun to carry in the field. The TC New Englander is also sought, IF you get a rifle barrel and the 12 gauge barrel together. (imho)
The CVA "mountain rifle" caplock in .58 also seems to be well liked..., I think for the caliber
The others are still made...Investarms makes several variations, so does Pedersoli, and Traditions is importing a half-stocked rifle too (they may even be a source for parts for old CVA rifles...not sure if theirs is from the same manufacturer as the old CVA...they look very similar....).
