They are almost identical to your 18-032 except the top hat section does not have the rear projection and the bevel is only on the front edge. They have stamped on the front edge "Windows Inc"

The 18-032 appears to be our best match. I'm not sure how much of a difference that rear projection will make. I'm afraid we've been unable to find this without it. It may work anyway. If not, would you be able to file it down 1/16"?
