I have a reproduction crank that I've tried, and it fits fine, so I think the issue is with the crank itself...the cotter hole in the crank is further out than on the repro crank.

I've readjusted the BB repeatedly, trying to see if that affects anything (it doesn't). I'd really prefer not to use the repro crank (made in India, off of eBay), because it's not made nearly as well as the original, and the cranks themselves are about 1/2" longer, a potential issue on a Twenty.

This situation appears to be a manufacturing problem from the factory, but I have a hard time believing an issue this drastic got past QC, or past the bike shop that sold it. So, I have to assume I'm doing something wrong, but I don't know what it can be. The spindle is installed correctly, long end on the drive-side. I've tried three different sets of cotter pins with the same result. I have NOT tried installing the NDS crank yet.

Is there a fix for this, aside from replacing the crank? What am I doing wrong?
I've run into this problem on the non-drive side of my '72 Superbe. IMO it is indeed a QC problem- one that would never have happened in an earlier decade. The 70s was not a kind era to the British 3-speeds! You can't adjust it out if the crank is engaging the BB hardware. Are you certain though that you have the correct BB axle?

FWIW dept: When I was a kid I heard this a lot in reference to British 3-speeds (with upright seating) but Master Sheldon is emphatic that such a term should not be used in this way.
