Paul from SWISCO responded:
Thanks for posting! Before I can offer an applicable replacement for your balance, can you first confirm the length of your balance? Based on the stamp, it may be 31".

If that is true, please take a look at our S377-31 channel balance with a 3030 stamp option and compare it to your own hardware. Do the shoes match up?

As for the take out clip, please look at our 16-023.
