Crank only, no sprocket, marked in center "A. S. & Co." on one side, numbers "3620-A" on the other. What year?

Thanks.

Re- check your number.
Probably 9620A Schwinn's part number for the crank arm post WW2.

Thanks for that. Think the first number just didn't cast correctly.

Also, I believe they resumed stamping the year on them in '61.
