BRITISH SALMSON 12/70 PH S4C
2-seater sports, sports tourer.
Same twin-cam hemi-head engine with alloy pistons and rods, but output up to 70bhp with an extra carburettor and raised compression. Remote-control shift and 4.75 axle where 12/55s are lower geared. Watch it, though, late (1936) four-seaters has the 12/55 engine, or so the catalogue said.
