Cool stuff Eric,
I too have been at work.
Last weekend I got two 200s at the fleamarket. I got both for $15. Both seemed to be in excellent condition. When I got them home I discovered that the better of the two had a super rusty pump tube. Somehow it got full of water at some point, I think its to far gone. So I took the best of both lanterns and built this one. It may very well be my best 200 A.

I got the pump cleaned and oiled.

It fired right up.

It is a very awesome lantern.
