Yes Dave, I wondered about that too.
I certainly didn’t fancy being dragged to the Tower and hung, drawn and quartered with my head stuck on a spike on London Bridge. So being an old civil servant I thought I’d call in a favour or two and check with Her Majesty. I explained what I was up to, how I spun up the coins and drilled through the face on my old Myford. She was a bit sharp. “The method is immaterial. We will not allow our face to be drilled into”. At this point I was a bit non-plussed but I had a sudden thought. “Do you remember George Formby? Your dad gave him an OBE in 1946”. “Ah yes” she said “such a nice man. He performed for us at Windsor Castle you know, in ‘41 I think it was. And all those sweet daft films, too”. Bingo, I thought! “Well, you remember “No Limits”? He rides an Ariel in that”. “Does he really? Well, in that case you may proceed with your Ariel and Morris Minor. We shall call off the hounds”.
So Dave, you’re in the clear. But don’t tell your Ford or Harley friends; I think her permission only applies to British classics. MikeN.
PS Thanks for the idea on dates. I'll look out for '56 & '63 now.
