Still no response via the Classic Caravan Forum. I take that to mean the question was to difficult. I must say I am a bit surprised that there is no response at all but there we are. Clearly Micronauts are more inquisitive.
The chassis plate offers the following.
PEKA
NORD - SUD - PLASTIK
Fabrik No - 593042 ----------------------- Baujahr - 1960
Eigengewich - 240 ------------------------ Nuizlast -
Achsdrucke - 400

I read this as model, maker, chassis number, date, towing weight, Do not know but no entry, max loading weight, brakes, no entry as there are none.
Thanks for the links. I found several myself. The tow hitch looks promising until you find that the caravan chassis is by Walter Winterheim. I need to see what happened to that company perhaps but it seems unlikely a company making trailers would be buying in chassis to make caravans and would end up manufacturing tow hitches. Anything is possible though. Also I like the idea of advertising Willie Gay's Peka!
