The balance has stamp: 2830 BS1 RO

Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 351 or our Series 390 balances.

Now, as you can see, there is only one difference between these two Series, and that 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.

Hello! This balance appears to be a match for our S395-36. This assembly comes with a 19-005 top and 15-001 bottom nylon fitting, so as long as those components match your original then you should be good to go. Lastly, based on your old stamp of "35 6," you will want to select our 3560 option when prompted.
