Identify these bikes! / Re: Villiers stationairy engine
« Last post by 33d6 on May 07, 2025, 09:43:28 AM »The first registrations I have around the GY 7000 mark date around the first half of 1936. Can’t get much closer than that. As I wrote earlier I can only broadly date when an engine was produced from registration dates. The registration dates are surprisingly varied, there can be a several month difference between consecutive engine numbers. It is very broad brush. Not that it matters that much as Villiers didn’t make annual model changes and the actual date of manufacture is irrelevant for maintenance and repair purposes.
As for the aluminium flywheel magnetoes yes, Villiers made them alongside the brass variety. Again, it’s not really relevant detail for maintenance or repair so I take little notice. Of far more interest are the paired numbers on flywheel and backplate to ensure you have a factory pair. Mix’n’match can cause problems here.
