Hello there. I am sure we can help, but can you show me the nylon attachment at the other end of the balance? We need to see both for identification. Many thanks.

Thanks. This looks like either an S351-29 or S390-29. The only difference between these two channel balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. In either case, for a stamp option go with 2830.
