Without dragging the thread too far off topic, submariner dolphins don't have a fouled anchor, for what I would have thought was obvious reasons. The Australian version has no anchor at all. The badge that the RN Submarine Service wears was derived from the RAN designed badge, introduced in the mid 60's here, officially recognised by the RN in 1972. All other Commonwealth navies then adopted it as a standard, with slight differences, the Canadian type being the most striking. Therefore, anyone trying to flog off a set of dolphins, claiming that they are from any time prior to the mid sixties at the earliest, are pulling your leg. Miniatures are issued for Mess Undress, Senior Sailors and Officers only. There is of course nothing stopping a Junior Sailor going to 'slops' and buying his other half (or halves ) a mini set as a sweetheart brooch.
