I agree, the S385-27 appears to be a good match. Just make sure your measurements are the same as ours, including those of the nylon attachments on either end. We would also recommend the 2650 option.

I think you may be confused. The 2650 option indicates the strength of the balance spring. You choose it when selecting your channel balance, right there on the channel balance store page. I did choose it based on your stamp of "26 5," yes, but you can always weigh your sash to be sure. We have a chart on the S385-27 store page that shows how much weight each option can carry.
The final decision must be up to you, ultimately. I can say that your balance looks similar, but the only way to be 100% sure is to carefully go over the information we show for the S385-27 balance and make sure it matches yours. Keep in mind that your stamp is not a product number. As I mentioned before, all that tells us is how strong the spring is. |
