Imagine the excitement at finding this little box. I mean, it had to be a old-fashioned, badly-shot blue film didn't it? It even had 'blue' stamped on it for goodness sake. And '1943' somewhere. The fantasy continued- would it be WAAFs being introduced to the finer points of timber barn construction by moustachio-ed parachutists, or girls in control towers being distracted from Lancasters landing with a wheel missing? With their headphones still on? But no. Oh, it's a blue film alright. A reel from Lindsay & Williams of Manchester that looks like it would be on the top shelf. Of the ironmongers. The end flap says: 'Parafilm is an amalgam of highly refined paraffin wax and pure rubber with the addition of colouring matter. Parafilm is thermo plastic non-hygroscopic, an excellent insulator and can be used with advantage in place of ordinary insulating tape, particularly in wet situations'. I don't think we need to dwell on any of that, do we? Thoughts on the aeroplane? An Avro perhaps?
