Greener made both "Cadet" and sporting miniature Martinis. The miniature Martinis that allow the entire action to be removed after the withdrawal of one screw were designed by Francotte.

The British were quite cavalier in their marking of .22L.R. firearms. Some were marked ".230" while others were marked ".22L"
