Thanks all... I didn't mean for this to be the Tuesday Stumper/Puzzler! I can't find any diagrams of it either online nor in my Randy Potter course... so IS it a Thayer action? Jon's description of the elongated knuckle is accurate. You can see the top of the elongated knuckle in the lower right foreground in the "side" photo. How would I regulate the jack-to-knuckle position. (not how do I adjust it, but where to I adjust it to?) There IS a drop screw. It's in the hammer rail, and there's an opening in the flange to access it. Not being a highly experienced tech nor much of a player, I would say this piano was much less of a monster than I expected when I first looked at it. It does really need pinblock (had to CA a couple of pins) and soundboard (well-cracked) but the action felt a lot better than most 1905-era grands I see. The case is another story. I think that every single case screw is weak, like it's either been taken apart and carelessly re-assembled, cross-threading and reefing them all too tight. The C88 hammer was snapped off right at the head. Long story, but I don't think I did it. I thought I'd have to diagonal-slice-n-splice a piece of vertical shank, but looked again and discovered that it uses standard vertical shanks. I just popped the shank out of the butt(?) at the flange end, pressed the stub out of the head, and glued in a new shank.
