History Vintage Sun Engine Tester..need help

Hey guys, just scored a 1952 Sun Engine Tester. I've managed to revive the entire thing except for the combustion gas tester. Does anyone know anything about these at all, or is there anyplace out there that still deals with this stuff? Not exactly sure where to look. Thanks in advance

 

Take a look at some of these links, for some ideas.

That's so cool man. I've been wanting a working one too for my garage.

 

@fordcrager That link comes up blank, maybe try it again?

 

Sorry about that, I revised the previous post. Another thing that you might try is the Garage Journal, there is a social group over there and some general threads, just do some searching.
