Here are a few photos of my trailer T3-C sn # 1291 - the tail lights are ones I made and added a bolt on bracket for the other side and replaced the floor, the safety chains were replaced at sometime too, the trailer is in mostly primer the red is the correct color over the od green. The bantam logo is a stencil of the one I found under many other layers of paint.  Most of the bolts are marked E.C or B.C.     I hope the info helps your site to save these trailers. The trailer is registered as a 1954 but believe it is a 45 or 46.
