I recently purchased what I believe to be a "pixie" suit.
I have struggled to pin point exactly when they were issued,
but the winter 1943-44 seems to be the date most people can agree on they were issued.
A heavy bit of winter kit, serge lined and with plenty of pockets.
Mine came with a hood, and has the usual "wear and tear" one would expect and some oil stains etc.
It still has the internal braces and it is a size 5. It will fit a man between 5ft 11inchs - 6ft.
I will try to get some better photos when possible, but you will have to make do with the following for now.
