Couple wacky cranksets that are awaiting the "just right" bike for them

Steel cotterless Gnutti with splined spindle interface. Luckily was able to score a remover, which is a different thread than anything else. Dunno how I ended up with three spindles.
And the Williams AB-77, that I did have one a bike for awhile, but I sold that bike and kept the crankset.

Again with the three spindles! I think in this case it's because someone gave me their spare parts after their left crank's splines got stripped, from riding it loose. I've heard from British guys who were racing back then, it got a reputation for stripping out the splines, but mine were reliable for me. I raced and trained on 'em and I'm big. Possibly user error.
