I don't know exactly when the VV was introduced but it
was made for decades.



Richard,

Thanks for the info, I will see what I can find. I have put up some
information and pics of the ones that I have at
http://www.radiowymsey.org/newsblog.htm . Mine with dials are the
original design - the earliest drive has 'patent pending' on it
whilst the rest have a patent number so I might be able to get a
date from that.


Charlie.
