According to this site http://chronomaddox.com/romans.html 861 movements from 1971 begin 26,27,28,30XXXXX

Was under the impression from a member that 1971 is 32XXXXX

Can someone confirm - or is there another reference?

Thanks!

Generally accepted is 31-32m

Romans list has been pretty throughly debunked.

If using the above listed website a 145.022-71 could be made from 71 to maybe early 74.

 

Thanks both for useful info.. I checked the number in the site works out it could or should be a 1971 based on the case back..

Is there such a thing as 1971 being rarer than a '69 due to limited production numbers? I know now we are getting a bit too deep

 

I'd say no. But there are some rare sub variations on the -71 dealing with the caseback
