[QUOTE="Simon Dinsdale, post: 138491, member: 58"] A few things to think about here so I have delve into the database. The crankcases casting type and mating number for JRO are well out of sequence and are from a lot earlier batch / type of cases. The 2nd Shadow made that went to Canada has a later mating number and later type crankcase casting correct for when it was built so I doubt very much it was built side by side with JRO 102. Consider this, the story is Philip Vincent when he initially proposed the Shadow he was told no by the rest of the board, so he went ahead and built it behind their backs in secret. Wether this is true or not I don't know, but that is what Roy Harper wrote in his books. If you are going to build a bike in secret you don't go to stores and draw out the latest parts as that attracts attention, you source parts from elsewhere such as the scrap bin and see what you can find. This goes with the story that Marcus Bowden tells that the first Shadows had reject porous cases, hence the early out of sequence crankcases on JRO 102. Using this info though I cannot find a 2nd bike in the records that is also out of sequence by a similar amount. Now if the fabled 2nd bike was never declared then what engine and frame numbers went on it as there are no missing numbers in the records for this period of time. If it was later declared then why doesn't it show in the records and why has it never surfaced since. The 3rd possibility is its just a good story and the 2nd protype never actually existed. Its probably one of those mysteries that will never be answered especially as the personnel involved are no longer with us. [/QUOTE]
