I think it's a '40's Fruehauf. That picture was taken of my COE back in the late 60's, or early 70's when the second owner still had it in Indiana. How ironic, it was purchased new, by a gentleman, that ran concessions, at Carnivals, back in the 50's. The second owner used it to spot storage trailers. I never could find a trailer like that, so I've recently removed the fifth wheel, & saddle tanks from it. Plan to install a period correct Holmes Wrecker, on it.
