posticon The link to a reliable DynaSonic Ser. No. date resource?


I have a COB DynaSonic I've used professionally since the mid-1970s with a Ser. No. 17700. I did not buy it new; it was used.

I know there has been some recent upheaval in the dating research, trying to make it more reliable (given the Rogers manufacturers were apparently a little haphazard with those numbers).

Is there a link to a "new" reasonably reliable resource?

Someone wish to provide a reasonable guess on the time of manufacture for my COB 5x14 DynaSonic Ser. Nol. 17700?

Thanks

Ser. No. 17700 dates it to 1968.
