Basement Find - need Marx transformer

Papa-D: 

Thanks!  This is great info.!

I also found this online searching for that set # (see link below).

Its funny (and sad) that the Guide book is selling for more than the train itself.

Also, found this, and what is interesting is that it includes 4 straight tracks and 9 curves, just like mine.  Doesn't 8 curves make a traditional oval?

This one also looks close, but has a raised spoke pilot, which mine doesn't have, so mine would be newer than this particular one?

And this transformer has 4 taps as you said...mine has 2

Almost exactly my set except for a different gondola

Not sure I beleive some of these car prices (3/4 of the way down the thread), considering what the entire set sells for.
