Ah, perfect. Thank you very much, Pat. I'm glad I asked to see this shoe, since this will have to be a special order.
You see, my first thought was that you need our S751-29 balance based on the design of your metal channel and the pivot you showed in your fourth picture above. However, this comes with a 15-014 shoe, while yours is instead the 15-197. We'll have to install the 15-197 onto the S751-29 here in the warehouse before we can ship it out.
Does that sound good to you? We'll also be using the 28HD stamp to match your original. Two balances with this stamp can hold up a sash weighing 22 through 28 pounds.
I'm going to email you an order link and price quote right now for 12 of these balances, but I highly recommend that you double check this information just to be 100% sure. You should just confirm that the 15-197 is the right shoe and that your sash weight falls in that range. If either of those two details is different than what I've surmised, please let me know and we can adjust.
Oh, one last thing. Your old balance used an S-clip to install at the top of the track. You can reuse your old S-clips, or you can purchase either our 19-029 or 19-030 (depending on what size you need). These are sold separately from the custom balance so I thought I'd let you know now, just in case.
