Home built in 1960 great windows window openers

A home owner from Lakeland, Florida 33809 says:

We just purchased this home great windows but I am missing 14 openers and cranks RUSCO patent number 2732726. I have three windows with working openers and two with no cranks the others have been removed and the openings taped over I will need the equipment and four screws for each window and one arm screw ( screw with smooth area ). 

I am not sure where you measured 5 and a Quarter inches these may be the same if measured from mounting holes to mounting holes. What do you think? Amazing windows but I need to get them to open again. Thank you. Ron

Thanks for reaching out to us, Ron. You have a very old style operator that isn't made anymore. However, looking at the design of the screw hole tabs on the top and bottom ends, I'm wondering if our 39-257B can be used as a substitute. This is a Rusco part and has a similar configuration. Look it over and let me know what you think.
