John

That is great information!!

Now....do you have the same info. for letter/date codes for Becker??

I have two Beckers with different letter codes and have been struggling to find the year of manufacture.

Thanks John

I have been on this Becker site before but it does not give the letter/year codes like you have done above for the Blaupunkt (unless I am missing something).

Many thanks again

I have bought some stuff from these guys, send them a mail and I am pretty sure they know the answer;

Thanks John for this info, looks like I am getting somewhere now. If my Frankfurts are indeed from 69-71 then they are no good in my '73 RS....I will probably sell them.
