Thanks for reaching out! It appears the balances in the first set of photos are a custom assembly. The depth of the shoe looks like it could be 7/8", which would be the 15-029. If so, this will need to be a custom made assembly. Can you please double check and confirm this measurement, written out?
In regard to the window with the missing balances, I'll need to know the height of the visible glass pane in the window; only the glass you can see.
I'll also need to see a photo of the pulley system installed at the center of the balance. This is where the string and the spring meet in the middle of the balance.
Please let me know if you have any questions in the meantime.
Thanks for confirming this information and for providing the photo, I am happy to get the order link made up for you. I'll just need to know the exact number of balances, per stamp, you intend to purchase. There is an order minimum of (2) balances per custom assembly.
Please let me know if you have any questions.
