One small point.
Queen Elizabeth made her son Charles the Prince of Wales in 1958 and his investiture was in Caernarvon Castle on 1 July 1969.

I have a Hamilton Bottle, it is frosted and is just under 9 inches long.
On one side is written in simple raised letters IDRIS and on the other LONDON.
I have no camera (yes really) and apologise for not having a picture - it looks like many others I have seen on EBay.
Can anybody help...
