"The manufacturer was Telefunken"

Telefunken became Temic and the Atmel W&M.

Hope this helps,

PS

I am not embarrased by asking 'stupid' questions, no insult intended, often when we (you and I) get frustrated we overlook the obvious. More than once I have been in a loop that I did not get out of until something so obvious that I had to slap my forehead was pointed out to me.
