This is a sterling silver travelling spirit burner.
It is a sterling silver box with hinged lid complete
with brass fitted interior used to heat ladies hair
The curling device rested on a pair of folding supports
and the iron was made hot by the spirit flame.
The silver box is decorated with a monogram (not
identified) and is fully hallmarked for Birmingham 1892.
The maker is Horton & Allday (1891 - 1933).
In this images It is accompanied by a hair curling iron
made by Mulholland Bros Inc. - Aurora, IL, active
between 1915 and 1932.
Oddly the seller was not aware of the existence of such devices
and the burner was put on sale as a "travelling inkwell"
