3/8 balancer & shoe

Hey, Robert. We should be able to help, but I'd like you to confirm a few things.

First, can you confirm the diameter of your balance? They never made a 3/8" balance with a black tip. Make sure to only measure the outer tube, not the inside spring.

Can you also confirm that the length of the tube is 28.5"? If it is, that's fine. We usually recommend rounding up to 29" in those instances. They no longer make balances in 1/2" increments.

Finally, concerning your pivot shoe, can you clarify what your dimensions represent? Is 3/8" the thickness and 15/16" the width? Height doesn't matter so much, but I assume yours is 1-15/16". Assuming that's correct, I recommend our 15-134. Look it over and see what you think.

I'm afraid I cannot guess on this information. It's not enough to go by to make a reliable suggestion.

Are you making sure to only measure the outer tube when measuring the diameter of your balance? Looking at your third picture in your first post, the outer tube appears to be missing. If you're just measuring the diameter of that bare spring then it will not be accurate.

There is no 3/8" balance with a black tip. No company has ever made such a configuration and it's not something we can provide. I am almost certain your outer tube diameter will be 5/8". I highly recommend double checking.

If it is, then our Series 600 should work well as a replacement.

They never made a 1/2" diameter tube in this style, either. Are you sure it's not 9/16"? If it is, then our Series 600 should work for that, as well. 

If you do have the Series 600 then you'd simply pick the Black Tip color option, which is what I see in your photos. 

When it comes to balances, you never want to guess or use estimates. It's important to be as precise as possible.
