I acquired a RNZAF nav brevet in the mid-70s. They used to wear it with shirts. They also had a summer lightweight forage cap.
Anyway I sold the badge on eBay and it was bought by an Australian collector. Turned out the badge as from the 40s even.
They also had a lightweight plastic pac-a-mac raincoat in recognition that it actually rains in the tropics. Used to good effect in Ascension.
Yes, we get it wrong all the time.
Can anyone tell me what happened to the blue 'KD' at Lyneham in '84?
