Hello there. Can you tell me the length of the metal channel, not including the nylon attachments on both ends? Can you also show me any stamp imprinted on the metal channel? I should be able to narrow this down from there.

Thanks for getting back to me. I believe this is either the S380-30 or S385-30. The only difference between these two channel balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe to see what matches best. For a stamp option choose 2950.
