I just drug home an old beat up trailer, to rebuild as a trail trailer. I began researching and found some pics on ECJ5 of similar, albeit not identical trailers. Does anyone have any idea if this was a commercial trailer or a brand or where a serial or vin might be? There is no tag that I can find. There were stake pockets at 4 corners, but they are rusted off. The floor is shot but the rest of the tub seems salvageable. The frame and axel is solid. Bearings and hubs are good. wheels seem salvageable. Note the weird hitch connector, square axel, greasable spring perches and shackles. I thought it odd that the tub is welded to the frame. Also odd that the spring perches are on "scabs" welded to the frame.
