I think these are sash or ventilation stops

A handy person from Virginia says:
I think these are sash or ventilation stops and one part has the letters "VSP" on the side. I accidentally broke the housing on both sides when I tried to open the window. The stops appear to be ok and in working order.

Hello!

We do carry a vent lock, our 26-387, but it is not exactly like yours. You will have to see if it can be used on your window. If not, you will need to contact the supplier of your window to see if they can supply you with an exact replacement.
