One of the first mention of the Primus Engineering system. It was in 'The Model Engineer and Electrician' magazine dated December 18, 1913
This 1916 Primus Engineering instruction manual is actually the 1915 edition with a stick-in label showing the 1916 prices.
This 1917 Primus Engineering instruction manual is actually the second 1914 edition with a stick-in label showing the 1917 prices.
This reuse of an old manual would be a wartime measure.
This is the 1917 Primus Engineering instruction manual with a "Prices Advanced" stamp on pages 3 and 7 to indicate it was issued in 1918.
Unfortunately it is without its front cover.
The 1917 trade brochure for Primus Engineering, showing their full range of products.
Unfortunately the original was in a very bad state.
