Here is a Charles Daly (Prussian of course, I don't work on the "other" kinds) BLE in 20 gauge that is also a two-barrel set. It needed the rim recesses cut because the original rim cuts were of too small a diameter to chamber any current shotshell. It also had a few other minor issues. The trigger plate screw had apparently suffered some damage, so an enterprising "gunsmith" widened the slot (a lot) in order to clean it up. The solution is, as usual, a new screw.
The threads on the triggerplate screw are proprietary, so after juggling change gears in the lathe, they were single-pointed.
Then, work proceeded in the usual manner.
After I engraved, case-hardened and "aged" the screw, that part of the job is finished.
The forend wood also need some attention due to substandard repairs, including the addition of a non-original screw to retain the forend tip.
After dissolving all of the epoxy, this is what was left.
The damaged areas were prepped to receive the new filler pieces.
The filler pieces epoxied in place.
The finished repairs.
