Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.
Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. 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 15-004 and 15-005

I can see that your balance is 35" long and would have a stamp of 3450, but I do not know what Series it is. You will have to follow the instructions Tom posted above in order to find the right Series.
