The only identifier I can see on the window is: SASH 32.937X29.125 - then there is some writing below that that I can't read with the number 3250 beside it.
I wouldn't mind replacing the whole bottom window but would be ok with just the latches that allow you to pivot the window in. I have 2 windows (same numbers) with one latch missing.
Please let me know if you can identify the window or part.
Thanks
