Personal mossie/bug sprayer and anti-mosquito cream tube

In a batch of one mans jungle kit acquired at auction many years ago was this personal sprayer, it would presumably have been used to spray a mosquito killer or deterrent, accompanying it is his double ended tube containing, I assume an anti-mosquito cream at one end and tablets at the other, most likely Quinine. As the tablets are really an unknown quanity they were disposed of. Photo shows actual items
