Tinker,
I can answer some of the questions + more.
- bls are 26" standing rear sight and two folding leaves
-H&H underlever rebounding hammers, pistol grip & cheekpiece
-Henry rifleing
-wt is 8lbs 9ozs
14 1/2" pull
Will need to get it out of the safe to measure breech face & chamber thickness etc
Whilst it is 3 1/4" case, it has exactly the same short neck and sharp shoulder as your Tolley.
