Broken window coil

Thanks for writing in. I'm afraid this coil balance is a little unusual to me; I am afraid it would be best to see the pivot shoe, or the part with the cam, to be safe. The identity of the pivot shoe is always a good way of identifying the needed coil balances or substitutes. If you could back to us with a picture of the pivot shoe when possible, we will do our best to identify what you need. Many thanks.

The coil spring manufacturer discontinued your style of coil spring. They recommend the 15-140 new style pivot shoe with S150-5 coil springs. We still have some of the old pivot shoes like yours, the 15-141; but that can only be used with your old coil springs if they are undamaged.
