These are 40 year old casement windows. The cranks are losing their finish. I would like to replace them with white cranks but cannot find any that fit. the I.D. meaures about .340 inches.

Hello!
Take a look at our 39-114 or the sleeker version, which would be the 39-114L. These handles fit in a spline that is 11/32" in diameter.
