Hi Guys, Can anyone help with details of a CDFW inter vehicle starting plug mounted on the rear left hand side of the above (what were inter vehicle starting methods pre and early WWII??), the spare battery crate mounted left hand side behind the POL cans and finally the flood lights and flood light box mounted behind the POL cans on the right hand rear side. Any help gratefully received.
Cheers T
