Pic dump:
From the top:
Felt bushing 'reamers' (files, really)
Hammer 'puller' for removing the hammers/shanks from an upright piano
Steinway wire bending tool (specifically for backstops on upright pianos, but usable elsewhere)
Mostly wire-bending tools, and a handful of specific screwdrivers/wrenches for pianos (necessity is the mother of invention)
A tuning 'hammer' (so called, since the factory tool was used to drive tuning pins into the pin block with a hammer)
A mute for silencing high strings during tuning
A block for propping the lid of an upright piano off the wall/piano/you while tuning
Old power drill. Yes, it still works, and I suspect, will continue to work far after I'm dead (it's on its third generation, currently).
Tool specifically for extracting XTR cranks, extant for only one generation. One side installs, one removes. Note the through drilled hole, for slipping a 5mm hex key through for leverage while installing/loosening.
Modern, high-quality hanger alignment tool. Not special, just most don't see these, I would imagine.
A pistol-grip, ratcheting screwdriver made by Schröder for Craftsman. The Germans were obsessed with ergonomics before it was a 'thing'.
