Hello,

With this combination of attachments, you could have either the S380 or S385 channel balance. I'd recommend double-checking the length of your metal channel since a balance stamped with 1950 would generally have a 20" long channel, not including the end fittings. You’ll also need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. 

If the length is 20", your stamp indicates that you'll need 1950 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
