Marvin window cranks

A handy person from Wyoming, MN says:
Looking for a replacement crank assembly - stamped with model #30830 - 1990 the windows were installed. Do you have something that would work for my setup?

Thanks, Randy

Sure, Randy. See our 39-216 and 39-217. These appear to match your hardware but just make sure the dimensions are the same.
