I'm trying to identify this channel balancer. My best guess would be a series 380 channel balance. Does that sound right to you?

I'd say it's between 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.
