I've received your pictures, but I'm having trouble making out what you have. Can you show me a clear and close up picture of the nylon caps on either end, as well as the metal clip at the end of the spring? Finally, is there a stamp printed on the balance? If not, we will need to know the weight of the sash.

Thanks. I believe you have either our Series 351 or Series 390 depending on the size of the bottom shoe. I can't tell from your pictures what the bottom shoe size is, but that's the only difference between the two balances I mentioned.
