One offs, manufactured by State jewellers were probably far from rare originally but given the exifgencies of time and distance now rank with hen's teeth! Some of the State regalia and awards are truly lovely and, sadly, some are of the order of 'Make it like this [official award] but shinier!'
Let's hope we get to see more closeups. I would say, that the bar is clearly hand engraved, which is to be expected. Haven't checked but I don't believe the original had bars as such, as the awrd itself was a single issue and pretty well self explanatory and self contained. Nice touch though!
