Who makes this tire machine?

[54 LS-3100]

Gentlemen,

I bought an old pneumatic tire machine this week, but can't find a make or model anywhere. I think it is missing the outside cover, but I figured the brand would be marked somewhere else.

The machine is complete mechanically and the only thing it needs it a new ram seal. I was hoping to find the make and model so I could come up with some schematics.

I thought it was a cool shop piece and couldn't pass it up for $20
