Need pretty much all the hardware for Truth 37.5 x 47.5 casement windows
I'm afraid I don't recognize the operator in your photo. It is just too damaged for me to make out. Do you have another window in the house that may have one that's still in good condition? If so, we need to see it out of the frame and shown without obstruction.
Thank you. My best guess at this stage is going to be our 39-036, along with the 39-035 for the opposite side, but please understand that this is mostly an educated guess. The original is just too corroded to properly identify. If you have anything else in the house that might be in better condition, seeing that removed would allow me to confirm.
Otherwise, review these two products and see what you think.
