replacement pivot bars

A contractor from Easton, Pennsylvania says:
I need to replace approximately 40 to 60 pivot bars and need something close in size to what is there now. They are windows from the Stephen Laurie company from maybe 30 plus years ago.
The picture that i added are what is there now and are spring loaded so you can take the sash out without tilting the sash, I don't need the sprig option just a bar that I can replace it with so the sash stays in place.
Regards, Paul

I'm sorry to say that I don't recognize this pivot bar. You mention that it uses a spring to tilt in, which is a very old style that isn't really common these days. The only thing we have that works that way is our 26-375. Could you possibly use this as a substitute? Look it over and see what you think.
