Many, many years ago I started collecting old uniforms etc., and one of the ones I acquired, from memory, some time in the early 90's, was a complete RAF No.1 uniform, with a Gieves & Hawkes named & dated label to January 1940. A friend of mine found it for sale in a local charity shop, having just got it in from a house clearance, so sadly likely from its recently deceased original owner.
Some years ago, I sold everything to a dealer, but kept that one because of its connection to the Battle of Britain timeframe. With time now marching on, I will need to start thinking about passing that one into the hands of a younger collector as well.
