i need new casement window operators

A contractor from Zion, IL says:
my neighbor has a right hand and left hand swing casement window. i need both assemblies. the arm says 07900 and opposite that it says "Wright". under the operator, if i recall correctly, it says 7720. i hope that having the measurements will help. THE COLOR IS NOT IMPORTANT, but if we can match it, great.

thanks for the help.

Thanks for posting, Dan. Start by looking at our 39-387 and 39-388 and let me know if these look like matches to you.

That looks pretty darn close to me. White is not ideal but it will work.

Thanks for the quick help.
