This is on a window in the bathroom. It is a very old house. I could not identify the logo, possibly "ACP". The window only has 2 horizontal panes that rotate. I have had trouble verifying the dimensions when comparing online diagrams.

Take a look at our 39-017 and see if that matches up to your measurements. I believe it is the closet one we carry to your operator.
