casement lock assistance

I'm looking for locks for my Marvin awning window from the 1980s. I have another Marvin awning window from the same era with locks on either side that lock in the same downward position (per the photos). Does truth make any such mirroring locks? I only found product code 38-075 that seems to lock in one direction. Please advise.

Also included is a photo of the window I'm trying to install them on. It has never had a lock. The crank broke and is missing in the photo. I'll also be ordering that piece from you.
