Agree Rob, they are nice mikes, and according to the link I posted earlier I would say that the examples pictured are all currently in production, virtually unchanged. I don't know how you would date them other than by serial number, and perhaps colour changes or other subtle changes in finish in some cases.
Rob.

G'Day Fellas,
I am by no means an authority on dating Mitutoyo Micrometers, but looking through my assortment, they have used 3 different logos over the years, the original cursive script logo seems to go back to the 1950s and 1960s, the all capitals logo from about 1970s to 2000 and the current leading capital "M' followed by lower case letters since then.
Regards,
Martin

Hi Ron,
As I said I'm no authority, and there does seem to be some cross over, my 1971 dated dial calipers have the all capitals logo. With used measuring gear, condition and price are more important than age to me, in fact I prefer the older micrometers with metal lock levers and ratchet knobs to the current plastic ones.
Regards.
Martin
