Thanks for posting. This appears to be either an S380-29 or S385-29. The only difference between these two channel balances is the depth of the bottom fitting, or the 'heel-to-toe' measurement. See the illustration below for reference. Measure the depth of your existing balance's bottom fitting to see which matches best. In either case, for a stamp option choose 2840.
