Thanks for the reply, Ivo....
If these have been copied in India and China over the last 5-10 years, what is it that they are copying? What have they been faking, in other words
What I'm asking is that if they have been worth copying, what might an original be?
- we have had this for over 33 years - were they being copied that long ago?
Sorry to pester you

Thanks again
Bob and Brigitte
