I don't know a lot about these. Just curious what I should value it at to sell. 40-hole . All gears work. It is stamped 55 and was on a Rudge. It powered all of the lights fine. I tried to get a reading on the power by putting my tester on the leads and spinning it by hand. It shows voltage, but I can't get it spinning fast enough by hand to get consistent or high readings. Thanks in advance
