Left and right bottom window hardware for bay windows. New cranks and locks.

Thanks for your post! There is a chance we can provide a replacement for the window lock, but I'll need to see the "inside" of it to identify what you have.

The hinge appears to be missing its track. This is the part of the assembly that the black nylon slider travels in. I'll need to know its length to determine the correct match.

Your crank operator can likely be replaced with the 39-318 Truth Split-Arm Operator. Although, to determine if this is the correct replacement, you'll need to be sure to review and compare the dimensions.

The opposite version can be found tagged below, along with the compatible handles and stud brackets.
