A Carousel double take

When I took the Carousel 10/2 Slimline folding caravan that I owned at the time to stay at Colchester Holiday Park, the wardens assigned me a pitch. A couple of days later, I returned from driving to visit local historic sites, to see that another identical model of Carousel had been assigned the next pitch to mine! It was unusual, because there are a number of different Carousel models, and their appearance has changed over the years- I had only seen more than one Carousel next to each other, let alone the identical model, at rallies.
