Bailey 14 ft caravan, photographed in the late 1950s

On my parents' drive at Telford Avenue, Leamington Spa. I was told that, after one holiday in a hotel with the infant sps1955, they decided never to repeat the experience, and bought the caravan second-hand. This must have been c.1957. My memory is that the caravan was a Bailey, in which case it cannot have been all that old when they bought it (the Bailey company had been founded in 1948: www.bailey-aboutus.co.uk/ ); however, it was kept until 1974, by which time it was something of an antique. I can recall only once seeing one like it and, indeed, I can't find photographs of any Bailey like it on the web, so I hope that the identification of it as a Bailey is correct. Any further information on the design or its history would be very welcome!
