1914 770cc V-Twin
P&M were poised ready to a launch a V-twin in 1914 at the outbreak
of WW1. The demand for the RFC model meant
that the twin never made it into production. This 6 h.p. 770cc (76 x 85mm)
machine had a four speed gearbox and, despite these radical changes, used
essentially the same frame as the 3.5 h.p.
model. (Picture provided by Volker.) |
1915 770cc V-Twin
The V-Twin was further developed and made it as far as the catalogue for
1915. These pictures show left and right views of the 1915 prototype. This
picture shows detail of the engine.I am grateful to Mats Berglind for these pictures scanned out of the 1915 P&M sales catalogue. |
1916 770cc V-TwinThe fourth prototype V-twin (HM 7) was built in 1916 and road tested by "The Motor Cycle" and was probably used by Richard Moore as personal transport. |
1928 500cc V-FourA V4 version of the Panthette was conceived of as a spoof for 1928, but never built. |
1940 500cc In-Line Twin The
Panthette
was the only twin Panther to make it into production and on to the market.
Granville Bradshaw (who also designed the ill-fated Panthette) built for 1940 this 500cc in-line twin. It has essentially the same frame as the Model 90. Apparently the sole machine built by P&M was used by P&M for over ten years. It subsequently disappeared and may still be in existence. Perhaps not entirely clear from this picture is the fact that the rear suspension is of a leaf-spring design. This parallelogram shaped system was a simple bolt-on upgrade to existing frame designs. It appeared in 1939 but had problems in terms of safety and costs. I am grateful to |
