Clicking around The Big Auction Site, I came across a listing for three sections of Hoge straight track plus an original box for six four* sections. The track looks pretty much like regular Lionel "O" but with different pins, (and they're arranged with two in one end, one in the other). The three pieces are quite bright and shiny, and the box looks fairly decent, too.
(I am in no way connected with this auction -- posting this merely because I thought some here might be interested in it.)
*The box shows the contents as a fraction of a dozen; it's hard (for me, at least) to make out the bottom number, but looking at it more closely (in light of Steve's post) it does seem to be 1/3, not 1/2, dozen as I thought.
