Have appended some photographs of a W.W. Greener No16.
The headstamp of this cartridge is not included in the examples shown in; ‘The Birmingham Cartridge Manufacturers, by C.W. Harding,’ (Page appended).
‘The Birmingham Cartridge Manufacturers,’ gives a guideline date of 1871-1950’s, but, very little information on the No16.
Would appreciate any additional background information?
