Hey John. If the metal channel alone is 9", then this is possibly either an S380-09 or S385-09 Channel Balance, depending on the shoe depth. See below. For the stamp option, it's tough to see what this channel is stamped. Check the other balance from this window. Otherwise weigh the sash to obtain a sash weight you can use to choose the right stamp option.

Comparison of the S378, S380 and S385 balance shoes.

The S380-09 Channel Balance is currently in stock and can be ordered via its shop page. Again, you'll need to verify the correct stamp option to choose. This reflects the strength of the balance. Let us know if you have any questions!
