2313 FG BSI Sash balance

Your balance looks like our S395-24 channel balance. I don't recognize the stamp printed on your balance, so I would recommend weighing your sash on a scale to confirm the proper option.

I'm afraid I don't know what top sash guide you have, either. Could you show me a couple different angles? I'd like to see it from the front and side, like a mug shot. I would also like its dimensions.
