Thanks for postig the pictures. They answer several questions: Yes, this seems to be a Series 1 LHD Sprint converted to RHD, with an original LHD engine, and a spare RHD engine that came from a later RHD Sprint/Spider. On both, LHD and RHD cars, Sprint/Spider engines were the same type and number range, therefore there is no information what the original car of the RHD engine might have been.More exploration ensues!
I have revealed the chassis number and original log book - 822218 - engine number AR00601*03296 so they appear to be original.
I made a typo in the post above.
The original colour was grey shown in the log book. I will be sending to the Historic link for certification.
So, series 1 converted to RHD?
The door handle is as Ruedi requested.
The block casting number shows wear or poor casting.
The engine number in the photo is from my spare - AR00608*00013 - and I haven't a clue where it came from.
Typos aside, I don't think you'll find any reliable information. In addition to this link I posted above, this car may show a reasonable approximation of what "Visone" might look like -- if you trust both that (a) the camera that the pictures were taken with, and (b) the screen you're looking at, recorded and reproduce the color with any degree of accuracy.My 1964 2600 Sprint was originally Visone. However, it has been repainted Alfa Russo. I am very curious as to what the paint color really was as Tubut indicates that is was limited to the 2600 Sprint. Is there anyone who can provide a visual reference for KF18011 or AR-273 or Ditsler mixture code 22490?
