Hi Ian and ODK members,
The month/year dating system on Villiers flywheels is only able to be used on post war engines. What needs to be understood though is that the date only provides an indicator of the year of manufacture of the engine and it is only relevant where the flywheel has not been replaced or exchanged. Both of the flywheels on my Centenary mowers are dated 10/7 or October 1947 so it is possible that these were from the same shipment of engines. Given that Ian's flywheel is dated December 1946 and his Centenary is numbered between both of mine it raises the question of when were these mowers actually assembled. The answer to this cannot be easily answered and can only be assumed to be somewhere between 1947 and 1949.
Cheers,
Sir Chook
