Hey, when did ever they start to put the blood group on the back of the tags as pictured above? Even my old alloy tags from the mid 1970s have not got this.
When I left the CF 10 yrs ago, I had the stainless ones with SN, but nothing on the back with the exception of the 'DO NOT REMOVE' in both languages. My early alloy tags only had it in english.
The above ones look alloy rather than stainless, and appear to be maybe even older than my 1976 issue ones. I do know the CF has had this design since 1951 or there abouts.
Cheers,
