Hey there. This might be an S380-29 Channel Balance, as it looks close. Please check the depth of the bottom nylon shoe, or its measurement from 'heel-to-toe'. See the diagram below for reference. The Series 380 has a 1" deep shoe. If your balance's shoe happens to differ, please let us know by how much. Otherwise, for a stamp option choose 2820.
