soft plastic hat by possibly W. R. Davies / Sharon Lee.
Although I originally believed this to be a Berwick item I am
now leaning towards it being a Sharon Lee product.
I don't think it came with any packaging.
I have recently obtained a variant of this hat - bottom
The colour is darker & the plastic a different texture.
It is also printed with a tartan pattern on the inner rather
than being plain. Perhaps it's Scott's hat........
