I recently ran into an action nearly identical to that Bechstein from 1885 picture some of you just got in that last bunch of pictures sent out. It actually was not dificult to regulate well at all, just needed a good offset screwdriver for the job. Played really nicely. I did an even SW and BW job on that and it came out beautifully.
