Allstate De Luxe
Also known as a 'Twingle' (split-single), two cylinders sharing a single combustion chamber. Late 'De Luxe' with aluminum muffler tips. This model number 810.94171 can be found with knee pad style tank, but there has been evidence as shown in the photos where it could have also been produced with the full chrome tank like the early De Luxe (unless someone had replaced the tank?).
