Balance coil

Thanks for posting. This stamp indicates that you have an 8 pound coil. However a number of different balance Series might use this stamp. I need to see pictures of the pivot shoe the coil balances attach to, preferably removed from the window. The identity of the pivot shoe will tell us the coil balance Series you need. Many thanks. 

This exact assembly is no longer made, but you can use our 15-259 pivot shoe as a replacement, as well as Series 159 coil balances. The video below shows you step-by-step what to do. Let me know if you have any other questions.
