Crank Mechanism for my front windows

A home owner from Hackensack, NJ says:
I need both a right hand and left hand crank mechanism with a crank handle for each.
On the bottom of the mechanism is "G U" & "patent pending, made in usa".
To me it looks like your model number "39-416" and "39-415".
Please confirm. How long does it take for shipping?

I agree, the 39-416 and 39-415 look like good matches. Just make sure the dimensions match up. Shipping time depends on what method you choose during checkout.
