![Marklin 468 D Straight Bridge OO / HO tinplate solid center rail conductor 1940s](http://lonestartrains.com/cdn/shop/files/DSCN0362_{width}x.jpg?v=1697357647)
You are looking at a vintage Marklin OO / HO #468D straight bridge--a metal girder style. This is the early style of track that has the solid center rail, most likely late prewar/early postwar.
This one is well used, but still ready for a new life on your layout.
See our other listings for a lot of two curved bridges in this same series.
CONDITION: C-6. Looks complete. All is shown for you. Oxidized rails need cleaning before use. Some rubs and scratches here and there. No box. Pictures show it all.
