It also could be that the brits crudely marked the barrel 45 AR so they would not put the .455 in the wrong gun over their and the barrel work was done cause they just needed a shorter gun or it was shortened some time after but at a time when collectors weren't in mind such as to meet their needs you know what with the WAR and what not.
