Group in a caravan park

This is interesting simply because it is the first APS film I've posted onto Found Film but there is something slightly more interesting as well. The slide is in a Boots plastic mount so was probably a film bought and processed at Boots in the UK. The actual slide mount is a 35mm mount however and it's possible to see the edge of the film which states it is Kodak film. I wonder if Boots film was actually re-packaged Kodak film (seems likely) or if this is just re-use of a slide mount by the photographer?

Because the film is APS, I've dated the image as 1990 - 2000.
