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.

Please see the attached photos. Let me know if you need any more. The channel is 30 inch.

Thanks so much for your photos. Based on what I see here, you have either our S380-30 or S385-30, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

The dimension shown above measures 0.89.
Attached are some improved photos for your ref.
Let me know if you need any other info.

Thanks

Gotcha, in that case your balance would have to be custom made with a 15-029 shoe, since this isn't a stock option. The 15-029 shoe is basically the same as those above except it has a 7/8" depth, which is much closer to yours.

Can you tell me how many you need? Custom orders need the quantity pre-set by us ahead of time. Once I do that, I'll email you a price quote and purchase link that you can use to place an order on our site.
