I’m hoping someone can jog my [failing] memory: Some years ago, the late John Belton wrote a short article on the Canadian 450 MH Line Throwing blank, an un-necked case usually headstamped “D.C.Co. 45 M.H.”. I thought (but I’m not 100% sure) the article was published in the Canadian Journal of Arms Collecting but I cannot locate it in those copies of this publication that I have.
Can anyone remember where it was published and in which issue, please? This IAA editor would greatly appreciate the help!!
