The mechanism has a code on it. OP05-7553-03. I think this is 39-329. The folding handle is PO5-7810 which I think is 39-226. There is a metal mounting type bracket attached to the window frame bottom that does not have a part number on it. It 10" long and has black plastic clips on either end. Looking at the window from outside it swings open from right to left.
Thank you.
