What was the last piece of equipment, developed or used during WWII, still in service with HM Forces. I am not just thinking of weapons and aircraft, but vehicles, plant, field catering equipment, and anything else you can think of.
There have been lots of suggestions; Mark 8 torpedo: Developed before WW2, this was still in Royal Navy service into the eighties, and was used in 1982 to sink the Argentine cruiser ARA General Belgrano. SMLE No4 Mk1: Still sniping away in the eighties, nearly a whole century after the first Lee Enfield rifles entered service. Gloster Meteor: Strictly speaking not in RAF service, but still working for a living doing defence work, testing ejection seats for Martin Baker.
The suggestion of the humble clasp knife may well be the one to beat though ....
