Great, just a couple of hours and you guys came up with 3 of the 5 items. Just one more tool photo, and I still need a side view of one half of a spoked wheel with a large flange hub because I believe it will be easier to see the spoke positioning.
I'm still looking for one #4 tool photo of an old, early wheel centering gauge from Schwinn. It's before Park tools got going, it's likely dated in the 1960's. It was a cad. plated Schwinn made tool. I don't believe it's even stamped with a name or number. It's just steel "C" channel formed. The indicator pointer is secured with a Huret shifter tension cup spring. It's older than Schwinn Twin Stick stem shifters.
Thanks, almost ready for the wheel building class to start.
