Kats, Interesting about the Z432 numbers, just goes to prove that it must of been a very exciting time producing the early cars. About the all solid metal emblems, Michael Hollander writes in "The Complete Datsun Guide" the following wrt the early car features: "Through approximately the first 2,200 cars, these badges were completely chromed with black accents. At that point, the letter "Z" on the badge was changed to a white inlay. Other markings remained the same. Thus the very earliest cars can be spotted by the chromed-colored "Z" on the badge." Not sure how accurate this is but it would be interesting to hear from anybody with a VIN below 2,200 and see what emblems they have. BTW, love your site, Gab
