An older picture of an Ebay auction showed up again in my documentation. I remember having it stored because of the seemingly odd, never recorded brick red colour.
At first is seemed to me to be a no. 551 Large Trailer indeed, an early version with ridged Dinky Toys hubs and grey round tread Dinky Supertoys tyres.
But then, looking more closely, and comparing with my own trailers, I realized that itâ€™s just its French brother, the no. 70 Remorque BÃ¢chÃ©e, the covered trailer, but now as a look-alike, being rather unrecognizable without the hood. The fresh, shiny maroon red of the new model has suffered in all those years, producing a kind of brick red colour, as used for instance for the early no. 501 Foden Diesel 8- Wheel Wagon.
And of course this has nothing to do with the real, late red no. 428 red Large Trailer which was available almost 20 years later!
Kind regards, Jan Werner
