"Not modified"
Wonder what he means by that as it's obviously modified with a tailgate, the drawbar casting is inverted and the lunette not present. Pretty certain the wiring and lights aren't original at this point. But that's ok because it's "not modified"
Though an actual Bantam trailer from WW2 is becoming harder to find. Many reenactors in the US have M100 trailers that have had corner handles cut off and and other things done to back date them.
