Here are some of my Rhodesian Air Force head wear
The Officer below Air Rank / Warrant officers dress cap and bullion and anodise badge dates from the 70's but the cap could be earlier as it is a UK made example and could have had the Royal RRAF badge replaced with the RhAF badge it is worn but in near mint condition.
The Officer below Air Rank / Warrant Officers beret and badge Dates from the late 70's and in unworn condition.
The Other Ranks beret and badge dates from the late 70's and is in well worn condition
I do have an Pre 1970 RRASF OR's dress cap but will have to take a photo at some time.
