A former GF’s father was an Aircraftman WOp/AG on 5 Sqn Wapitis over the NW Frontier pre-WW2. He was an Armourer. Retired as a flt lt and ended up as WpnEng (something) at MoD as the Desk for all rifled weapons in the RAF … including Tornado 23mm and 76mm in the Regt Scorpion tanks. Quite a span of history.
