This is the best comparison I can find of the 2 different trailers, the area above the towing point at the front is completely different and I'm told the bottom pic which is more straight through (my model) is the late version not used in Africa where the top pic is , I'm told, the early version and is more cranked and matches the photo I posted carrying the Matilda and every other pic in NA that I can find. In fact I can't find a photo of my straight through design anywhere so I don't know what references Thunder used.
