I stumbled across this spoon and thought it might be interesting simply to show Rhodesian silver hallmarking conventions. Which I did not know existed. including a date letter <Q> for 1978. Now I am not sure whether they had a 20 or 25 letter cycle and included I and J but it may be of interest.
The spoon has the Rhodesian crest on it and was one of a limited edition of 1000 made by Scottish Jewellers of Salisbury. It's not a particularly attractive or well made item, but it does come with a tag explaining the hallmarks.
