The 1/2 stock is a .62, .50 for the full stock.
The Flinter's lock plate was plain, like the cap lock when Taylor received it. He turned it into an Ashmore with the appropriate carving and sculpture.

The lock was on a different full stock flint Hawken that went through a fire.
Taylor re-hardened and tempered the springs and frizzen and left the colour as recovered from the ashes.

Also - the cap lock's stock took the aqua-fortis from the same bottle, quite differently than the full stock. Both are finished literally, identically, yet the cap lock's stock is so much darker.
