[Phelon & Moore](/source/Phelon_%26_Moore) made motorcycles in [Cleckheaton](/source/Cleckheaton), [Yorkshire](/source/Yorkshire), from 1904 to 1967, and branded them "Panther" from the 1920s onward.[1] Launched in 1932, the **Model 100** was made until 1963. While the engine and overall layout stayed essentially the same, the specifications evolved over these three decades.[2] ## Development 1937 Panther Model 100 A 598cc engine was used in the Model 85 Redwing (previously Model 80) from 1929 to 1930, and the Model 60 (previously Model 3) from 1928 to 1935. The Model 100 engine was largely a development from the Model 60. The earlier engines had compression ratios of either 5.4:1 (Model 60 pre-1930) or 7.0:1 (Model 85 and Model 60 post-1929). The frame is derived from the 1928 Panther and the tank from the 1932 Model 50. The history of the development of the Model 100 is as follows.[2] **1932** - Model 100 launched. P&M 4-speed gearbox, Webb forks. **1933** - [Sturmey-Archer](/source/Sturmey-Archer) 4-speed, hand-change gearbox introduced. Frame redesigned.

This new bottom end remained almost unchanged for the next thirty years. This machine had a 6.5:1 compression ratio, 87 mm × 100 mm (3.43 in × 3.94 in), ohv sloper engine.[2] The 1935 Model 100 was the machine on which Miss [Florence Blenkiron](/source/Florence_Blenkiron) and Miss [Theresa Wallach](/source/Theresa_Wallach) undertook the epic journey from London to Cape Town, crossing the Sahara: the first such journey on a motorcycle combination.[3] **1937** - New fully chromed fuel tank with red and black lined cream panels and snarling Panther logo.
