I was surprised to find out that the left balance is a 19-D-40 and the right balance is a 19-E-50.
This window was made by ORAN in Ontario, Canada. They are out of business now.
I found replacements on different websites but they don't have the same bottom piece as these have.
Also, these have no top piece, the top is held with a screw beside it. Do you have anything like this available? Thanks!
