needing awning window cranks

A quick learner from illinois says:
The crank replacement is for an old Howmet Aluminum Corp. which I believe was their Homet Plant Playroom. It is all aluminum: sides, ceiling with skylights and awning windows. Please help if at all possible.

Hey there! Thanks for shopping with us! To help us help you, can you please send us photos of the part that needs replacing? Do you just need the crank handle or the entire operator?

Hi Donna,

Thanks for your photos and drawings. I could not locate your Howmet operator from any of our suppliers. I'm thinking our 39-058 operator could work, but also take a look at the 39-280. These appear to be the closest to your measurements. Take a look and see what you think. Also, check out the the video I've posted on replacing awning operators. Let us know how you make out.
