Schwinn crank ID (stingray?)

[Mr. Kool]

I have a crank which looks like an early stingray but no date stamped on the middle.

The only thing stamped is this: A 2 0

What does it means??

Thanks a lot for your help. :wink:

You sure it's not stamped "AS Co." Arnold, Schwinn & Co. Gary

I could be all wet, but when I see these marked "A" - I think it stands for Ashtabula, which I think was a foundry.

Could be Ashtabula, which was a huge bike parts supplier out of Ashtabula, OH. They made tons of forged forks for Schwinn so likely made them a few cranks too. Gary

So, no way to date this crank?

Not from those numbers. Let's see a pic of the rest of it. If it's a dog leg, it's likely prewar or early postwar. If it's smooth sided then it's likely a 50's or newer. Gary

I've had a few Schwinn cranks like that, I hoped for a date and they had the same markings. as yours They were all from 60's Schwinns.

Have to clean it before taking pics but arm length seem to be 5,5.

All stingrays cranks don't have dogleg??? What about length?? 4,5 or 5,5 for pre-66 ones???

Oops! My bad. No StingRay ever had a dog leg crank. Early shorty StingRays definitely have a shorter crank. Gary
