The only thing I can find is a stamp on the back. I think it's  28B,or 288

Based on your photos, I would recommend either our S380-29 or S385-29, depending on the size of the bottom shoe. I'm afraid I can't determine your size by photos. You'll have to measure yours as carefully as you can and refer to the pictures we show for each balance.
