Try some McLube colorless (I think it's 444) on the termination points and under string felt. Otherwise it's the pin block. Baldwin was notorious for jumpy pins. Nasty. With a 40's Wurly, its most likely termination points, not the block, unless rust has settled into the pin holes. Don't lube those at all. Is there rust and crap on the strings and/or coils? You could try to loosen the junk build up by jerking the pitch low and then bringing it back up. BTW, Wim won't talk you down if you don't start it. Take a nice breath in and out now. He's a really good guy if you give him a chance. So is Joe. So am I for that fact. We all know a lot of good stuff if you let your defenses down and listen.
