Biltbest cranks

A home owner from USA says:

I have two windows with Biltbest cranks. One is very hard to operate, the other is I think stripped as it just spins with no movement to the window. I think they original to the home that was built in 1969. What parts are needed? How to repair? Picture attached.

Thank you in advance.

Hey, Sara. Could I see a few pictures of this operator removed from the window? That will help us come up with a good replacement. You can remove it by gently prying off the wood trim that covers it and then unscrewing it. Let me know!
A quick learner says:
I can't take off the wood, or I don't know how. I could give you a picture with the window open if that would help to see the arm?!?
I'm hoping to hire a window person to so the work, but everyone I talk to seems reluctant that the crank can be fixed.

Hey Sara. Seeing the arms with the window open is the next best thing, yes. However, we will also need to see the tips of the arms, so if you can disengage them from the window after they're open, that'd be perfect. Let us know!
A quick learner says:
Here is a picture of the arm. The end is attached to a roller that is in. Track on the bottom of the window.
Thanks for your help.

Thanks for the additional image. The closest I was able to find was our 39-013. Do you think you could adapt this for use in your window? You will likely have to redrill the installation holes.
