Please Identify
Hi there!
Thank you for reaching out to us. I'm afraid I don't recognize this balance at first glance. I can't promise we'll have a suitable replacement but we'll try our best. Would it be possible for us to see photos of the top fitting? Can you also confirm the length of the metal channel?
From your photos and dimensions, I believe you may be able to use the S385-26 which comes attached with the 15-004 bottom shoe (1-3/32" depth) and the 19-005 winged top guide. Based on your old stamp, we recommend the 2540 option for your replacements. A pair of balances with this stamp will support a sash weighing 19 to 25 pounds. Take a look and see what you think.
