On the Double Action Lifter and the Mainspring Tensioner,,looks like Pierre originally got confused and struck the serial# with the 'B' where the '6' was to go,,then used the 6 to over stamp the B

On the Frame, it was originally assembly number B15,,then overstamped B17.

At least two different sets of the larger size stamps used plus a small size.

They certainly knew how to make busy work at the St Eddie shop didn't they!

Great pictures and an interesting revolver too.
Thanks for posting them.
