As promised the Jersey white helmets. I have four of these, the first two are the Pith helmet introduced in the 1890's these originally had the centrepiece of the helmet plate as the badge, this was later changed to the shield collar badge and finally to the cap badge.
The other two helmets are versions that were ordered in the 1990's as samples for possible introduction in the summer months, however, the idea was not proceeded with and the helmets were given to me.
One is like a foreign service helmet and the other is the Royal Marines style.
As it happens the white helmet was re-introduced in 2012, I am still working on getting one for my collection!
