Unfortunately the photo of the rear of the trailer is a little hard to see - but there appears to be some discolouration on the photo around the rear lights
-making me wonder if the aread the lights
are sitting is raised a little bit? or the rear lights
may have been changed out. May just be the photo though.
If I am not mistaken Scamp
in that time frame used rectangular lights (not unlike what is on it) did they not? and not the round wedding cake type they used on later years. The lights where flush to the trailer - fiberglass wasnt raised or recessed where the lights where attached.
