1/2" channel balance with unusual stamp

A contractor from Walnut Creek says:

Greetings, I need to replace several failed 1/2" non-tilt channel balances in the bottom sash of Wausau aluminum double hung windows. The stamp reads "2517 BSI ML 26L" The balances are 26" long. I don't believe you carry the Wausau top & bottom guides but I can reuse them from the existing balances so all I need are the balances (and some rivets!).

Thanks.

Thank you for your patience in this matter. We are having trouble finding a replacement for this balance. Can you tell me the depth of the shoe? That is, it's "heel to toe" measurement. Can you also tell me the weight of the sash? Finally, I would like to see both the top and bottom nylon attachments from a couple more angles. Hopefully we can find a substitute!

Heel to toe of the bottom shoe is 1-3/8", the upper guide is 1" depth. Sash weight is 26 pounds, window is designed for 2 balances (1 each side) per sash. As I mentioned, I can re-use the existing guides if needed by drilling out the rivets and installing in the new balances.

Thank you. I've been unable to secure the exact fittings for you, but I believe I came up with a possible alternate solution. Look at our 19-009 top fitting and 15-095 bottom shoe and let me know if these could work for oyu. I would also recommend an option of 2550, for a sash weighing 25 through 28 pounds. What do you think?
