Alan,
The edging lines are unusually pronounced on this medal but I note that his KSA was not issued until June 1912 so perhaps the machine used was different then? I don't know when his QSA was issued, presumably January 1904.
As you say, his medals are correct as per the roll. I have been collecting the details of extant DoM medals and Crossman is not someone I have seen before.
So, other than the price, I think these are OK.
Best wishes
David
