Thanks for your patience during this busy season. I actually don't recognize this balance off-hand, but give us a little time to look into it. This will very likely have to be a custom order, assuming it's still something we can get a hold of. I'll try to get back to you ASAP.

I don't think we can supply this exact balance, unfortunately. One Series we have that I think might work is our S795-27. This is a 27" long metal channel with a 1-1/4" wide T-Lock shoe. I would also recommend the 27C stamp.

One major difference is that our balance is screwed to the top instead of using a hook in the top hole. To remedy this, you would use a 26-200 screw plug and a 33-090 installation screw.

Look these parts over and let me know what you think of my suggestions.
