Topic: Is this Master Cylinder worth keeping?

[Zi.gg.y]

Hi everybody

as far as I know, my 1966 SJ convertible should have a jar style master cylinder, but it came with this. It looks like it have been there forever, so my question is: Could this be original or is this a replacement? And if its a replacement, what brand is it? The only other car I could find with a similar master cylinder is this 65.

Not an original one.
