Mystery 4-cyl oscillator

[MRA]

Hi folks
This came my way recently - found in a scrap bin at a college. I wonder if anyone knows who made it, or anything about it?
Thanks
Mark

I saw a dealer (probably Forest Classics?) selling these at a show 10 years or so back. I thought (from vague memories?) they were made by toy maker SEL.. but I was wrong as it seems to be this Unit Steam Engine company. Mazac castings, from what I remember.
Thanks for the memories.
