Hey, thanks for posting. I've narrowed these down to two possible channel balance Series: either our Series 351 or our Series 390.
Now, as you can see, the only difference between these two Series is their bottom shoe. The Series 351 uses the 15-002 while the Series 390 uses the 15-001. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match. Comparison of 15-001 & 15-002

To determine the option for your balances, simply refer to the stamps printed on your balance. In your case, I would recommend the 1520 option, 2020 option, and 2220 option for each balance, in order (22B usually corresponds to our 2220 option). If you still aren't confident, you can always just weigh your sash and look for its weight on the chart posted under each Series 390 balance in our inventory.
