Balace
This looks like either a Series 380 or Series 385 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. Review the illustration below and let me know which you need. We can provide these balances for you at this unusually short length via a custom order. Can you just also tell me the stamp on the metal channel? How many of these do you need? From there I'll prepare a quote for you.
Hello again. Yes, sorry for missing this detail earlier. We can provide a 9" Series 385 for you via custom order. Can you just confirm for me what the stamp on the metal channel says. From there we'll prepare a quote for you.
Sure, it's printed on the face of the metal channel. I can actually see it in your second photo from your first post, imprinted in the metal itself. I think it reads "8 2" but I wanted to be 100% sure since it's a little hard to make out.
I just sent you an email with a custom link to order a pair of these 9" Series 385 balances, stamped 0820 (the equivalent to 82 or 8-2). Let me know if you have any questions prior to placing this order.
