@forty2 I've been stalking old iron drills like that one for a few years. Whenever a good deal pops up, I never have the time to snag it or the room in the garage to rehab it.
@WilliamHeath That's a beautiful instrument!Best way to clean the keys is with something really light and soft.Stay far far far away from anything abrasive on the keys. Else you'll be wheel buffing each one to get the finish right again.
