Hi Moggy
What a shame they're not in your mum's loft - do you think your friends will give them back if they have them!! 
Of the two friends who came with me, I am still in frequent touch with one, but the other I haven't seen in a long while. However been in indirect touch through third parties, so I hope
if they have them there shouldn't be a problem.
I've seen it.... felt it.... and now have a piece.
Thanks so much Moggy!
You're all welcome. As I said, I have had this stuff filed away for 36 years. Good to share with those who appreciate. Should have taken the entire room down!
