Not the drilling in first pic two in a row on one side , then 2 on the next. Strange dont know what it came from.?
I think when my son ordered He gave them , the inside of rim hole measurement, between the dimples, this should detetmine, wether its drop center or not. The Buchnans guy thought it might be a Harley rim, but I doubt it. For one we reangled 3 rows of holes, and it looked like hole was angled different from one side to the other....to me it suggests a hub with one flange larger diameter than the other. HD are same diameter, both sides like our Hondas.
At any rate all spokes are about 1/8 or more past end of the nipple, so I say cut too long.
The Truing stand is a Dudley... it's 80 to 100 years old.
