You are bidding on an old, postwar, mostly unmarked, Lionel, maybe a few are other makers, lot of 11 metal car frames with a few extra parts, as shown in the pictures. Most are in the 8 to 9.5 inches long range. Very good shape, surface rusting to some as shown, general scrapes and scratches, a few parts, a few have more wear, all could use some cleaning. Zoom in for details.
