Hi Arty & Beech,

The first mower is an Atco light mower they were a new post war design. They began production of the 12 & 14 inch first About 1946/7 with the 17 & 20 inch versions following in about 1950. This mower has the cone clutch and sideways facing pepper-pot exhaust which makes it most likely a 1952/3 mower. The clutch changed in 1954 to a plate clutch and the 20 inch mowers received the 98cc Villiers engine in place of the 79 cc Atco Villiers engine.

The other mower is was made in 1948 and was the model produced between about 1947 and 1949/50 before going to the light design. Engine is a 147cc Villiers. Flywheel date is 1946 but this may have been swapped at some point.

Kind regards,

Sir Chook
