Hi Luke,
OR's badge which has been fretted, not by a board soldier, we do not have any
I would say it has been done by a local craftsman, found where ever the British Army are stationed overseas, I have a similar KOSB badge which was fretted I believe in Cairo, its a bit more intricate as he has done the regiments title and the lower motto, normally the lower motto fretted were Sergeants badges.
On the pushing out of the centre this is a normal practice by soldiers, I for one did it to my own KOSB cap badge, not long after the rebadging parade on 17th July 1969, pushing out the castle by placing it over the open top of a milk bottle and tapping down with a top of a broom handle which was prefect for the job with acceptable results
Nice badge by the way.
Best
Hiram
