Nice rifle. Looks like a slanted hook breech,,I think that was correct for the rifle/period.
The opposing flat drilled & plugged vent probably not true to the originals,,but perhaps so. I'm no Hawkin guy for sure. The Knock's breech did use the system though.

Nice workmanship. Fix that forward tang screw slot that someone decided was loose!
I think the screws on it were all 'qualified' when it left the factory, even the escutcheon wedge plates. A couple have probably been challenged over time as to wether they were tight enough.

53,,54 cal,,, That's interesting. Very unique that a mfg'r took the time to replicate the original spec like that. Much easier to take an off the shelf dimension that a bbl maker was already in production for.

FWIW,,Most M/L bbls (for round ball) are measured and quoted by true bore diameter.
The groove will be .010 to .012" more generally depending on the mfg'r.
A 50cal bbl will be .500" bore and (usually) .510" groove.
