I remember a time before kids and school fees when i could get to Swinderby (for those that do not know, it is a huge antique fair close to Newark and in Lincolnshire) and had money to spend. Probably nearly 10 years ago, and there was a man there selling PY weights. However, I think he was not passing them as genuine, but as "fakes". He told a story of having bought many of them some time previously believing them to be genuine. I think they were reasonably priced. I should have bought some!
I googled Ramon More but nothing obvious came up.
