Strange 3pdr with circular headstamp not in the usual British style. Looks like dots form the letters rather than punch marks.
Headstamp 3PR QF BLANK GB MK 5 2004 GMT
Has a 5mm rifle primer, a steel pipe insert about 150mm long inside, and a 4mm mouth ridge. Chrome plated and 248mm long.
Who is GMT? Is this something made up for saluting blanks for easy reloading, and chromed so it doesn't corrode or swell the case after many firings?
Any information appreciated.
Thanks, Graeme
