I uploaded pictures of the broken one on the right side of the casement for a left hand window and a functional one on the left side for a right hand window. I have not taken it apart to find any additional markings, however I believe it is probably an Anderson or maybe truth hardware?

Hello, thank you for posting,
Please start by taking a look at the 38-209 or 38-205 escutcheon and handles. Review the overall style and dimensions of each to see how they compare to you original. Let us know what you think and if you have any additional questions!

The 38-209 looks close but the dimensions are too short.

Unfortunately we do not carry the 38-209 in a longer version. I apologize that we are not able to provide a direct match.
