Back in the eighties there were some petrol powered Flandria cylinder owners being sold in the UK. Can't remember who by but the distinguishing feature was that the drive to the cylinder and rear roller was, I think, by large nylon? gears rather than chains. I believe that they were made in Belgium and that at one time they may have been distributed by Victa as an addition to their range of rotaries.
Google throws up a few hits , mainly related to entries in auctions and side wheel push machines but nothing of much interest. Does anyone have knowledge, publicity material or even a machine lurking in a shed?!
