32D - BSI - RJ Channel Balance
Patent 4610108 on round end piece of hardware
Has a metal hook on end of string.
Thanks for posting. This balance will have to be a custom order due to its configuration. Thankfully, your pictures tell me everything I need to get started. I'll email you an order link and price quote right now for two.
They are different, yes. Your old stamp would correspond to our 33C stamp, which is for a 33" long balance that can support 20 through 25 pounds.
To confirm, please measure the length of your metal channel to confirm that it is, indeed, 33". I would also like you to check the width of your shoe, from "ear" to "ear." I twill be either 1" or 1-1/4". Finally, can you confirm that yours has a hook at the top instead of a screw tab?
If all that information lines up, all I need you to tell me is the quantity you wanted to purchase and we can get the ball rolling on this.
