This is the Topi, Topee or sometimes refered to as a "Solar Topee". An Anglo-Indian Title.

A Bit on the small size......about 54. Otherwise in very fair 90% (or more) Condition. Interior Sound and Complete with Chin-Strap etc.
"Quartermaster's Comment":- Note how it has an Owen No. 3360 Cap Badge. Michael tells me that it was worn by just about all 'Other Ranks' of the British South Africa Police.
