BSI 2630

Question

I am trying to identify this non-tilt balance.
I can't seem to find any top parts that match this one. It appears to be BSI 2630. The metal is 27". But the parts I am finding don't match either the style or measurements I seem the have.

It seems to me that this is probably a S385-27 with a 2630 option

The top attachment looks different, yes, but it should still work. After all, the top attachment isn't that complex, and you can get away with minor cosmetic differences. As long as the shoe measures 1-3/32" deep like the photo below, you should be able to select a Series 385. Then, verify the 27" length of the metal channel, and verify the 13 to 19 pound sash weight (because 2630 can hold 13 to 19 pounds).
