Looking to replace all of these parts

A home owner from New york says:
Hi there I need to replace all of the parts for this bow window. I do not know the window manufacturer. The window lock has no part number on it. The crank mechanism has the numbers 30905 on it and the crank handles have the numbers 40083. I would need two left side of everything and two right side of everything. Can you tell me what to order? Thanks!

Hello,

Take a look at our 39-171 and 39-172 operators as possible replacements. As for your casement lock, we have created a list on this page of possible replacements since this is an older model that isn't made anymore. 

Thank you!

Are you referring to the hardware we suggested above? If so, all orders can be placed directly on our site at your convenience.

If I'm mistaken, please let me know exactly what you need and we can work from there. Photos of your own window would be very helpful. Even if your hardware seems identical to what's shown above, there still might be differences we have to take into account.
