Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

My brother got this Steam Engine but it has been messed with in the past and the glass tube is busted/missing (along with the lower screw).

I sent photo's to Jensen and the nice lady thought it was 50s / #10.  With so much missing she suggested converting it to fuel pellet - which is what I think a previous owner was trying to do to it.  There is some kind of a metal shelf inside that moves pretty much freely inside.

I do have the option of sending it to Jensen but I was told they most likely wouldn't be able to make it back proper / electric.

Thoughts?
