Balance with 62-105 Hook

Question

I am looking to order 6 of these balances.

There is also a long S-Clip attached the top of these balances.

Please let me know if you need any other info.

Your balance configuration isn't totally uncommon, but the stamp is very peculiar. Before we go any further, can you confirm the length of the metal channel and the weight of the sash that it supports? That would give me a better idea of how to calibrate this spring.
