Starts at zero.

Is this not a 240z speedometer?

Series 1 start at 20, and series 2-3 start at 10? 

Is the date code on back 23 01.3?  The first digit is hard to make out.

I swear it says 23, but maybe it smudged during the print and it's supposed to be 73.

So if it's 73, then each series 240z got their own speedo?

69-1/71 /20mph

71-72 /10 mph 

73 /0 mph

 

 

 

 

 

 

 

 

 

 

I looked at few original 1973s on Bring a Trailer of Money and it looks the same as my 1972 speedo.

Maybe @kats can hopefully chime in??? 🙏

FWIW, here is a comparison of 240Z speedometers as shown in the 1970 thru 1973 Owners Manual pdf scans I have collected.
