Hello, thanks for posting! It looks like you could have either our S351-29 or S390-29 with the 2840 stamp option. The difference between the Series 380 and the Series 385 lies in the depth of the shoe. Take a look at the picture below for more detail. Once you have determined this dimension you should be able to select the appropriate balance.
