hello Once again since the club website up dated the club as missed out a Heavy twin In history of Heavy twins and some time ago there was a long conversation and a thread put on the website About this missing heavy twin but to up date you all again now there is three heavy missing twins Now how as this club managed to miss these out of Heavy twin history its not good is it for you historians that supposed knew every Heavy twin made Now I will up date you no these models number one the 1946 Jack Moore 500cc Heavy twin rebuilt by phil Hannah and riden and displayed and no recognition given by this club next number two the 1950/1 Model 77 ridged export model some 235 built for export and last the 1959 unit construction 650 rebuilt two of them hand crafted by Anthony Curzon small pages of this motorcycle was written by Frank Westwood in roadholder But not one word in print on this website about these Norton twins in Norton Twins History Not good is it when others need to find out about these extra Rare Norton Motorcycle's Time to put thing right Or do you want me to write in these Extra rare Norton twins Yours Anna J
... no wonder there is little written about them.
Anna the club is a group of like minded enthusiasts who appreciate their particular model and are interested in the history if someone has knowledge to impart about an obscure machine born from the same company then please feel free to educate us. I'm sure the editor would love some new copy.
Maybe a "historian" role should be created so these gems could be compiled into an overall marquee history.
In the meantime your offer to write on these would be interesting...
Then there is the 1942 twin 350cc, yes drawings exist for parts of it and some old piston catalogues still list the pistons.
hello well this club is not helping its self by not putting in history these missing models and prototypes this mean the Norton where trying to do some R&D where in most write ups its tells the classic and vintage motorcycle public That Norton did No R&D witch is wrong As they did do R&D and testing on the dynamiter And even had the police to Bracebridge factory when running the Dynamier as it was water cooled and ran across the street some complained about this Yours Anna J
This is great stuff! I suppose we don't know about the development models because they were blown to bits on the dynamiter, what a waste
The unit construction 650 twins, that I had built into two different frames, could have been back in 1960, have been Norton's first production oil in frame, frame bike. One of the AMC drawings for this oil frame, frame, shows the frame mounting location's for a single, twin, and the unit construction engines. Therefore, AMC and Norton would, could have built, and produced oil in frame bikes, in the 1960's. This was a full ten years before the Triumph oil frame twins came out in 1971. AMC and Norton, were looking at all possibilities, for their future products. As hind sight is 20,20 vision, it is so easy that we can now think, that they did not try, as so many of these ideas, were scrapped and sent to be melted down. Many of them were saved from such an abhorrent fate, and only through those that worked there, that some of them were saved from such a fate. The oil in frame, framed Matchless G12CSR is still a complete bike, as I own it, and three of these frames were constructed, back in 1959 to 1960. One went to Australia, but it has since disappeared, and it had a Matchless G80CS fitted to it. One, was destroyed in a road accident while out being road tested by Brian Slark, so only one remains, from this very innovative frame idea.
The history exists, just that no one knows where it is or who has it, which is shame. Sadly, as those with the records can see that where the first models of type where taken for experimental / test use, nothing exists to say what happened to them thereafter.
Ladies and gentlemen, I would gladly publish items regarding these 'lost' Norton machines - not just Heavy Twins (I wrote a short item some years back about the prototype 250cc Norton Single.) All that is required is for knowledgeable members to write the item(s) and then submit them to me. I personally don't have sufficient knowledge or sources of information to do this myself and I suggest that reliance on the Club Officers to produce all of this is a little 'one-sided'. So please get writing/typing!
The Unified Twins were not recorded, in any of the Bracebridge Street twin records, as it was then a very secretive project. This the late Neval Hinton informed me, when I asked him for a club dating letter, so that I could register the first UT. I spent many an hour in the Science Museum, looking for any recording in the factory dispatch records for these engines, or even a complete bike. None of these engines have engine numbers, only casting numbers, or a PD number. this stood for Project Design. Bill Cakebread who worked on the Norton twin P10 project informed me when I told him about this engine, that he did not know any thing about its inception or that it had actually been constructed. There have been two articles that were written for Roadholder about the two different framed UT's and also twice in Real Classic magazine. I was told by the late, Brian Jones, that there was at Bracebridge Street a factory book, for all their experimental engines and bikes, and this was known as their PD book. In all my research, I have not had any one else who has admitted to seeing or knowing of this book. That would be some thing to see and read, if it could ever be found and its contents recorded.
