Hello, Thanks for posting! It looks like you have either a Series 380 or Series 385. The difference between the Series 380 and Series 385 balances lies in the shoe.The series 385 balance has the 15-004 shoe which is slightly larger from front to back, as illustrated. If you measure your shoe as it is pictured below, you should be able to determine which one you need. Comparison of the S380 and S385 balance shoes.
