These the two plates you mean ?


I have listed it on the WA register, but couldn't find the US site you mentioned - at least, not one that has any 260's on it. Do you have a link for the site you mean ?
The engine number is L26 093773. Is anyone reproducing the Nissan type plate ? If not, I might get my contact in Germany to reproduce them as I have them reproduced for early Mercedes.
UPDATE: Still can't find anything that relates to dates relative to engine numbers, but I did find one site that indicates the 260 2+ 2 was produced from October '73 to Aug '74, with chassis numbers from 000001 to 015000. Based on 11 months production, at an average of 1364 per month, this should put mine as being produced in the first month of production i.e. Oct '73, but it would be nice to be able to verify it. Does Nissan have something like a Classic Centre or an archive that you can write to for details ?
