Crimea medal; heavy brigade charger

[dante]

The fighting Irishman; Recent purchase from an online jewelry store in the USA.
As many will be aware for collectors the Crimea medal is fraught with difficulties, issued unnamed the naming found was for the most part privately undertaken, some engraving has been attributed, but most have not, those medals most at risk from forgery have been light brigade chargers, the thin red line and those whose lives are well documented.
Johns Crimea medal has been engraved by a yet known engraver and at some point, the clasps have been removed and put on in the wrong order. 
Roy Dutton whose monumental work on those who took part in the Charge of the Heavy Brigade published in 2008, confirms that 1128 Private John McGuire, 4th Royal Irish Dragoon Guards took part in the Charge, no other details were available.
Having purchased the medal for the cost of an unnamed no clasp medal I set about trying to find John McGuire.
For two days I went through every John McGuire on “Findmypast” on the second day under the 4th Hussars I found him

Is this Johns medal, to be 100% is almost impossible, but for me its his and while much of his life is still a mystery, taking part in two or more cavalry charges makes him a hero,  who is not forgotten.
