1934 Soyer 500cc
The firm of Soyer & Cie produced motorcycles between 1920 and 1935.
The company was originally established in Colombes, France and later on moved to Levallois.
Soyer was one of the very many French makes that used a variety of proprietary engines for their products, although they also produced their own power sources.
JAP, Sturmey Archer and Chaise were among the engines that were employed.
This particular machine is equipped with a fierce looking OHC face cam engine of Soyer’s own manufacture.
Only five of these exotic sports machines are known to have survived.
This particular machine has been part of a French collection for a long time and it’s a well-matured restoration.

Two Pushers
Boulton Paul produced a whole family of low/medium altitude fighter designs and derivatives in answer to the Air Ministry’s spec F6/42. Here we take a look of two of them.
Boulton Paul P99
A pusher, twin boom layout with the unusual placement of the tail fin right in the middle of the tail plane. The cockpit was well forward giving excellent field of vision for the pilot.
Boulton Paul P100
A contraprop pusher layout with advanced swept main wings to aft and high mounted canard wings forward, immediately behind the extreme forward cockpit giving excellent field of vision for the pilot.
While offering many advantages, the prop pusher layout had one critical problem. That being, in an emergency, pilot escape was a very risky exercise in that the props would be in the direct path of the escaping pilot.
Boulton Paul envisaged a novel escape system being adopted on both P99 and P100 designs. The forward lower third of the fuselage directly under the cockpit would hinge out and down like jaws to allow the pilot to escape.
While the Boulton Paul designs attracted much interest, they were rejected by the Air Ministry as being “too advanced”. In fact, many features can be seen today on modern fighter aircraft.
