Looking for a non-folding crank for this 12-tooth spline. The narrow part of the spline (where there are no teeth) measures somewhere between 1/4" and 5/16" diameter, as measured with manual calipers. The wider base of the spline is about 3/8" diameter. There are 2 sets of teeth with a gap between, presumably for a snap-on crank.
Thanks!
