Need help identifying this part for replacement

Question

Not sure what kind of windows I have as I cannot find any sort of name on them anywhere. Only thing I found on one window is a sticker saying"134066 Bot Sash" and on another window "F-67516".

The point where the window pivots is completely broken and the pivot bar itself is also bent. Looks like just the metal part that turns is damaged, but would rather replace the whole thing. Likely get more to replace and update others on window or to have on hand just in case.

Thanks for writing in! Your coil balance pivot shoe has been discontinued and is no longer available. However, the good news is the 15-177 Coil Balance Shoe should work well as a suitable replacement. Take a look over the dimensions and compare them to your existing shoe to confirm that this is a fit for your window.

This shoe is compatible with the 1/2" thick Series 152 coil balance springs. To determine the correct spring strength for a particular sash, you'll need to look for any stamps/markings on the metal coil(s) in the window. If there are no stamps/markings or they are hard to read, you'll need to obtain the exact weight of your sash. Once you have the sash weight, you'll divide it by the number of coils in the window.

You'll need to secure the coil to the shoe using the 33-072. You may also need the 15-143 coil bushing, the 15-144 coil bushing cap, and the 15-145 coil bushing.
