Pivot bar

I'm afraid it's difficult to determine the identity of this pivot bar from these photos alone. It is still embedded in the sash, and appears damaged. Can you remove one from the window, preferably a whole version, and show us? That would be very helpful. Also, if you could tell us the distance between the mounting hole used and the tip that fits into the pivot shoe, that would also be most useful. From there, we'll do our best to find a match for you. Many thanks.
