30842-R window crank

A home owner from Cedar Rapids Iowa says:
30842-R is the truth cranking mechanism in my current windows. Are either your 39-035 or 39-036 compatiable as a replacement part? Thanks. Regards,

That number you gave me is actually associated with a bunch of different operators. I'm afraid I can't confirm whether our 39-035 and 39-036 can work for you. We have detailed photos and dimensions on their respective store pages that you can use as a reference, though. 

If you still aren't sure, please upload photos of your operator here for me to review. I will need to see as much of the operator as possible so please make sure that it's not obscured by the window frame or anything else.

Hi Tom. Thanks for your followup. I've included 2 photos, but I don't know if they will give you what you're looking for. I will try another window if these don't get the job done. Again, many thanks. Regards,

I'm afraid your photo only shows the base. I can't see the arms, which are just as important (if not moreso in this case). Like I said in my previous post, I have to see as much of the operator as possible. It cannot be obscured by the window frame.

Happy Friday Tom. Here are a few more pictures that I hope are more helpful. Regards, Scott. Also, I saw a different Truth # on the device...30842R

Thanks, Scott. I can confirm looking at these photos that our 39-035 and 39-036 should work perfectly well for your windows.
