I can only congratulate the War Dept section that dealt with procurement of male undergarments in the late 1940s. They must have placed an order for delivery in 1952 for long johns. Some or all of that 1952 delivery stayed on shelves until 1979, for that was when my long johns were issued to me at RAF Leeming as an RN snottie. Only seven years older than me, they continue to serve me very well.
Is there any other MoD equipment delivered in 1952 (or before) that continues to work as well as my long johns?
