Thanks for reaching out to us. It looks like you have either the Series 351 or Series 390 depending on the depth of the bottom shoe. You'll have to measure as shown below to determine the proper Series. If the balance is stamped with the number 2410, the metal channel should measure 25" long. Let me know if you have any questions! Comparison of the S351 and S390 balance shoes.

Can you tell me what you got for the depth of the bottom shoe? It could be that it was worn down over time from use depending on the dimension. |
