The numbers on the reverse are as follows: 111957023E 1.66
Written in blue ink is: 36 1.66
My beetle is a "D" registered (registered on 7th Nov 1966) so a 1967 model.
I have asked a few questions about the speedo to the seller but don't think he knows much about beetles. He us advertising the speedo as a 1966 year. Do you think the serial numbers match to my car?
