I think we can help, but I'm afraid I can't confirm based on the stamp alone. All that tells us is how strong the spring is. I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.

I looked through your balance selection but did not see anything that matched the broken balance, in the pictures the locking terminal has been damaged with the metal part that the pivot cam locks into being pulled out it proper place, also apart of the broken pivot cam is in the slot in the locking terminal, thank you for your help.

Thanks for the additional information. I recognize this balance. It was made by a company that went out of business, and is no longer made. That said, we should still be able to help. Consider our S795-31 channel balance with stamp of 31E for sashes weighing 29 through 33 pounds. I think you might be able to get this to work as a substitute. However, you would need to take out the 1-1/4" wide shoe that comes with it and replace it with our 1" wide 15-194. What do you think of this solution?
A quick learner from Vermont says:
Yes that solution sounds great, I look forward to ordering several balances with the alternative bottoms when I return from vacation. You have been a tremendous help and Swisco is a great cite for people who are looking for replacement Balances for bonneville Windows , thanks

just getting back on the project now, and i found a few potential problems the solution using the S795 series. In my pics bottom of the balance has a shoe a single piece of plastic that goes back up 1.5 inches in the channel and has pulleys. and there is a plastic guide that goes on the top of the balance,

If the Series 795 balance will not work, then I'm afraid we have no other possible replacement. Your old balances aren't made anymore, unfortunately. Since these are wood windows, a local mill work may be able to make new jamb liners for you. These would come with all new springs, and hopefully they'll be more modern.
