on the bottom of piece it says pat. no. d-212-686. it's from an andersen window, at least that's what the customer said, although the patent comes up as amerock.

I believe you have the older style Andersen window pull, which isn't made anymore. See if the newer style 26-224 will fit the cut out in your window. Also look at the surface mounted handle 20-015. This is another style Andersen uses.
