Center fire breech block is in

[treebeard]

The new center fire breech block came in today. It is a close fit but no cigar. Off to SORi and some cautious fitting. Total disassembly and cleaning which work has kept me from since it came in will be first order of day.

The best advice I read before fitting the block was to carefully measure the original block, then try to make the centerfire block match it.  Mine took very little work to fit properly.  BTW, while you are doing a cleaning its a good time to remove the lock and do a safety inspection of the sear and tumbler notches.
