Looks like you have a 3/8" thick spiral balance tube with a 15-020 nylon shoe attached. Please compare dimensions to the Series 300 balance, and see which one you need.

It's 5/8" or 9/16"

In that case, you might have a 5/8" Series 200 tube balance with a 15-010 nylon shoe, or a Series 303 with an extended spiral and the 15-010 shoe. Please compare and see if either of these is the right balance for you. The plastic color will be different, but check the size.
