Thanks Geoff for the suggestion , I speak german, german grandchildren Etc, i've had searches running on ebay.de for about 10-11 months.
I kick myself I gave one away and I've seen dozens for sale over the years.
But because they are obsolete (analogue that is) they have disappeared.
I'm sure that one will turn up somewhere. I'll be in Germany hopefully before Christmas I'll be calling in a few dealerships to ask if they have one on a shelf out back I guess.
