The only way to get most of the guards armor is to kill a guard wearing it (or hope one dies in a attack) and maybe with a lot of skill stealing it from them, if the guards have been replace i don't think you can get the armor. You could maybe check any farms or small settlements see if any were left behind, the guard at Left Hand Mine at least should still be a Markarth one due to a bug.
