• Hi there, what a find!
    It looks like you have the fore runner of the Rotoscythe Eton model, you are correct to say villiers engine on that machine as yours dated from roughly 1935,Although its lost it original colour on its hood.Rotoscythe did use Bux engines from 1939 onwards. Hope this helps

  • Welcome. The Rotoscythe engine may not be a Villiers, I know early Rotoscythe machines used a Bux engine.
    If you could post a photo of your Monrotiller and if it has it the machine number I can date it and give you some more information. Monrotillers are my speciality. It might be worth starting a new forum post for the Monrotiller.
