Hi there!

I'm afraid I can't identify your balance from this photo alone. I would need to see clear photos of the top and bottom fittings to determine a match. Your metal channel should also measure as 35", not 33". Can you confirm that you only measured the length of the metal channel?

I didn't measure wrong. It is 35".

Thanks for verifying. Based on the design of this balance, my first recommendation would be the S395-35. This comes with a 19-005 top and 15-001 bottom nylon fitting, so as long as those match up to your old fittings then you should be in good shape.

This one is the same as the one I have. How do I know what option to select? Stamp says:
34-4 AA CMC 4
What weight rating do I select?

Based on your 34-4 stamp, you would need the 3440 spring strength option.
