Thanks for posting. I'm confident we can help you replace this, though we will need a bit more information. There should have been a tube wrapped around the outside of this balance, probably made of white plastic. Can you tell me the length and diameter of this tube? Since the diameter of the inside spring is 3/8", I would bet the diameter of the outer tube was 5/8". If that's the case, look at our Series 600 spiral balance.

OK, The pix I sent was w/o outer tube, thanks for your diligence.

The outer tube dia is 27/64, (3/8)

Series 900?

Ah, gotcha. If the outer tube is 3/8", then I recommend our Series 900 instead.
