Window opener, KK marking.

I have a bunch of old window openers, some are missing covers, or cranks. I'd love to replace them with openers where the crank can fold in, or else with a small profile butterfly turn.

See our 39-107 Cover and 39-205 Folding Handle--or, see our 39-0107FK Handle & Cover Kit. So long as the spline diameter is 11/32", either option would work for you.
