Thanks for posting! It looks like you have either the S351-32 with a 1" shoe or the S390-32 with a 1-1/8" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. You'll also want to double check that the length of your channel is 32".

Comparison of the S351 and S390 balance shoes.

Unfortunately, I am not able to cross-reference the stamp from your balance with those on ours. That said, to determine the correct stamp, you'll need to obtain the exact weight of your sash. 

There is a chart below the product description of both balances that lists the weight ranges each stamp can support. If the sash weight is more than 42lbs please let me know.
