Trying to id this old vinyl replacement window

A home owner from new jersey says:
Spaced bar in IG says ROVO-80. 1st photo is the tilt lock mechanism. 2nd photo shows the handles and locks. Let me know if you need more photos.
Just beginning to fix them and I am sure I will need a variety of parts.

Hi there- thanks for posting!

Please look and carefully compare our 26-116 handles and 26-120/121 top tilt latches to what you have to be sure. 

I will need to see a better photo of the lock and keeper to be able to determine a replacement for that. 

Thanks!
