1912 Excelsior Rear Wheel Spoke & True

This thing is tricky.  Spokes 'click-in' slots on one side, opposite inside direction, different spoke swags, angled clincher rim.  I had to disassemble it, and it's like a huge Bendix Red Ring coaster brake inside.  All dry, it needs cleaning and greased.  Then reassemble and see if I can get this 26" hoop in a truing stand ?  It's got two different ways to hit-the-brakes (internal and external) - and driven by pedals or the motor . . . The engineers couldn't make up their mind what they wanted.  A bicycle?  or a Motorbike?  Transportation for either of 2 markets.
