tilt window balance 37B GK5 CMC 4

Thanks so much for contacting us. We may be able to supply this balance, but based on what I see here it may be a custom assembly. With that in mind I'm going to need more data to verify.

To start, can you show me a clear photo of both the stamp and the top end of the balance? Can you also show me a clearer photo of the clip at the end, and whatever pivot shoe it might attach to?
