Tilt Latches for Single Hung windows

A purchasing agent from Renton, WA says:
Our client is looking for the tilt latches for the vinyl single hung window. They told us that it was Milgard window's single hung windows. We showed all the photos and information to Milgard window's service department, but they are sure that their single hung window had never had the tilt latches and it is NOT Milgard window. The have never seen that type of the tilt latches on their (Milgard) windows.

We have no idea which window company has this type of the tilt latches. Our client is looking for 40 pcs of Left Tilt Latches and 40 pcs of Right Tilt Latches.

Can you identify this tilt latch? One of the attached photos has the detail dimension of this tilt latch.

Thank you,

Thanks for the detailed dimensions, Danny! They're a huge help. I would start by looking at our 26-120 and 26-121. These seem like a match to me, but see what you think.
