Replacement window latch

I need to replace several window latches. I'm not sure of the right name for the kind of windows, but only the bottom part moves. So you know what I'm talking about, I'll call the lever part that I move to lock the window the "handle" and the part that engages to actually lock it the "tab".

On the latches I need to replace, the handle has broken off, so the window has to be locked and unlocked with a screwdriver to slide the tab.

The latches are all stamped "Champion" with 5 interlocking rings. The mounting holes are 2 1/4" on center.
The locking tab extends 3/8" when locked.

Do you carry this part, or an equivalent?

Regards,
