131 forum posts 9 photos | The reason for my query was to find out if by chance there were any more out there. There are examples in the three major vehicle museums, I have a couple and i recently made contact with another private owner. So I was just hoping. Edited By Roger Hulett on 28/07/2016 10:14:43 |

Bet it handled uniquely with small front wheel with engine hanging off one side of it. . Be grateful for small mercies ... [if I understood the description correctly] there is a flywheel on the other side. MichaelG. |

![]() 7468 forum posts 230 photos | According to one site I looked at, it said that it tended to be a "bit" unstable due to the motor mounting possision. Ian S C |

131 forum posts 9 photos | It is quite true. The engine is 140cc single cylinder o.h.v. air cooled. The bulk of the engine is on the right hand side of the front wheel and is counterbalanced by a large cast iron flywheel on the left hand side. The spindle of the front wheel is linked to the engine directly by gear wheels.There is no clutch or gearing. Starting is by raising the valve lifter and pushing.The combined oil/petrol tank is mounted over the front wheel.There is no brake on the front wheel but the rear wheel has the benefit of a band brake.I understand that the early models (1919) did not have a seat for the rider and this refinement was only introduced in 1920. I have most of one Mobile Pup,3/4 of another and 1/2 of a third. I am not an engineer by trade and have had to learn/muddle my way through a great variety of engineering and casting techniques,and as I live in a fairly remote part of Wales,I rely very heavily on You Tube. If anyone would like to correspond with me on the subject of the renovation of a Mobile Pup,I would be most grateful. |

3 forum posts | Having just joined the forum after a number of years buying MEW, I browsed through the various topics and found this one. I feel I can add some history. Thomas George John was born in 1880 in Pembroke Dock, won scholarships to the Royal College of Science, was a Whitworth Exhibitioner and worked for various well know companies before buying Holley Brothers in February 1919, mainly for the premises and skills in Coventry. An early venture was involvement with Stafford Auto Scooters Ltd in the motor scooter, the Stafford Mobile Pup. The frame was supplied by The Birmingham Motor Guild and the engine was built and fitted by T.G.John Ltd. Apparently Mr Stafford had a shop at the bottom end of the TGJohn works in Hertford St. TGJ went on to found Alvis Ltd for the manufacture of Alvis motor cars. The above is a synopsis of the early pages of the book produced by the Alvis Register entitled The Vintage Alvis. Two members of the Register own Pups and one was part way through restoring his. |
