24 3 balances

Handy Person from Portland, OR
I'm trying to determine which replacement part to purchase. Attached is a photo of the stamp on the channel balance. It looks to me like it says "24 3 BO CALDWELL"

Thanks for any help you can provide!

I'm not sure what you have, unfortunately. We have dozens of different balances with that stamp. It's not a product code or anything, it just indicates the strength of the spring.

In order to figure out what Series this is, I need you to remove an undamaged version of this balance from the window and show me clear pictures of the top and bottom nylon fittings. I will also need to know the dimensions of these fittings.
