still very strange for afghans
however the bearskins for scots greys and grenadier guards is not a myth
you can read it in the regimental history on the HP of the units....
(same with Napoleons mounted grenadiers after Marengo)
and yes, the original "Pickelhaube" was a Cuirassier helmet fitted with a spike on service dress
later copied in the Albert helmet, from which the actual "bobby" helmet derives
the prussians and russians derived it to the lower version
but I guess you know that anyway

however, what surprises me is that a rather european fashion of adopting "captured" uniform did spread to afghans....
but anyway, as it is....
so you could actually paint british colonoal highlanders as regular afghans - why not
