Publish it here Sir, or be forever open to redicule!
I've got the same photographic evidence. However it appears to show a slim(ish) regiment officer in a No 6 parading with aforementioned "standard" It cant possibly be me, so I'm not going to publish it!
Re The Rhodesia Medal - this was an official medal awarded for service in 1979/1980 during the lead-up to Zimbabwean independence. Definitely authorised for wear, or if you prefer you can always flog it - on the rare occasions they come up for sale they can make around £500!
