You also didn't mention if you want custom, semi custom or just standard entry level or production rifles.
If the latter...
CVA offered a Kentucky in both 45 cal cap and rock lock and a 50 cal in cap, as well as a Pennsylvania 50 in both cap and rock locks... all R/H. The early Kentucky's were starter level finished, but the latter Kentucky's and the Pennsylvania's were well made.
As for Thompson Center, only a few full stock traditional rifles got out of the factory. But they were basically just Hawkens with long, slow twist RB barrels and full length high grade walnut stocks. Would be very hard to impossible to find one for sale though. I know, I tried for years and the only two I finally located couldn't be bought for all the tea in China.
Traditions has/had a Kentucky, but I know nothing about them.
Cabela's has the Pedersoli Kentucky and Blue Ridge that might be worth a looksee.
