BestBilt casement window cranks

A professional from USA says:
I am a licensed General Contractor, wrapping up a remodel on a house we bought to flip, and have it for sale now. In doing final clean yesterday, I noticed the windows had some issues.

The windows are BestBilt casement windows, and while most are vertical, some are horizontal.
They all appear to use the same hardware, the old 233D.C. style in gold.
The cranks have a white plastic knob on the end.
I'm pretty sure these were circa 1979 or the house was built around that time I believe.

I have 2 bad cranks and 1 bad handle, but will buy 3 of each so I have a spare.

I believe they are all right hand, as the cranks are located on the right side while looking at the windows from the inside.

Photos attached.

The wand/bar with the teeth on it and the pivot wheel are fine, so I really just need the cranks and handles.

Do you have these in stock?

Thanks for posting. Bilt best is no longer in business, I'm afraid, and we suggest using one of the newer style operators. The bad news is, you will likely have to make a new wood sill cover, in addition to other adaptations depending on what hardware you choose to go with. I don't know exactly what can work for your window, but look at the list I made on the right side of this page. This will at least get you started.
