We can help, but we'll need more detailed information. The stamps don't identify the balance, they only indicate the spring calibration. In order to identify each balance we will need clear photos of the top and bottom nylon fittings. We recommend removing an undamaged version of each balance from the window to ensure that all the important details are visible for us to review. Thank you!

Thank you! This is a huge help. I think I have a good idea of what you need, but if I'm right then this will have to be custom made. What I have in mind is a unique combination of attachments. Because of this, I'd like to be 100% sure.

I believe you have a 15-029 shoe, which is 7/8" deep, as well as our 19-037 top attachment, which has those same skinny wings. I'm very confident that the 19-037 is right, but I'm less certain about the 15-029. Can you confirm that your dimensions match?

Dimensions for 15-029
Assuming I'm right, I'll go ahead and email you an order link and price quote for each of the sizes you've requested. If you want to make any changes, however, please let me know here in this thread and I will be happy to do so.
