Need to find these screen retainers

A handy person from Indianapolis says:
These screen are wood framed and installed in the interior side of older Pella awning windows. I have not come across anything similar so far. Not sure how old the windows are but the house was built in the 1960s. Thanks for any help you can provide.

Hello,

We don't carry an exact replacement for your Pella screen latch but out 70-218 looks promising. Take a look and see how the specifications compare. Thank you!
