The first AC cranks did have a window cut through, but the later stronger ones did not.

Those are definitely AC cranks, but I don’t see the logo, so they might be the generic UMC version. BTW – don’t ride them, I broke two sets on the driveside, crankarm just snapped in half leaving a very jagged edge that made a scar I still have today.

I think I remember these as AC experimental or low run production cranks. IIRC, they took their standard cranks and milled out the rest of the windows but halted production after high failure rates.

Grafton

ROOX cranks, s*** brand from Holland Europe IIRC

definately AC cranks! I remember lusting over those as a teenager, then magic motorcycles came out and AC were a thing of the past.
