Where in my Post this A.M. did I say we did not have one of these SF #12s in Blue, and what makes our collection the proof of a known Lesney variation's non-existence if we do not have one. There are thousands of Superfast variations we do not have, but they do exist. I really don't care about our early Superfasts, I do have a comprehensive early collection of variations, but my current interest and focus is on my preferred regular wheel variations. Please re-read my quick Posts this A.M. that made me late for work Mick.
Also, Please see Nick's online Guide for the factual story on this early blue model that completely agrees with our 41 year old NAMC SF Guide on this variation. If a Facebook Post by Mark Curtis from 2014 means that much to you Mick, what 44 year old facts can I print here that will hold any water now?

kwakers suggestions to Mick: Pay Nigel Cooper for a copy of his comprehensive Lesney Superfast Guide that was written and documented by him as these Superfast Toys were released. You will be amazed at the variations that may not have yet been documented anywhere else, but do exist. If you do not have access to his or any other very early Superfast information that you need, Please do not speculate and present negativity here on our Forum without studying period publications that pertain to these known documented transitional color variations. Are there 'fakes'? YES! Do they make any originals less valuable? Only if they are found NOT to be the original rare blue transitional SF many collectors are searching for.
When veteran collectors Post answers to questions you need answers for Mick, read them and spend a few days doing research before commenting negatively about ancient texts or the knowledge they may be able to help you with.
If you want to speculate about Lesney 'Fake Variations', do that on Facebook, not here on Nick's Forum that we are trying to keep factual and historically accurate. Outing Fakers is Good, speculating and creating doubt about rare Lesney variations is not very Positive for our hobby. kwakers
