I certainly do Frank, I was next to him on one occasion!! I too bought some pieces, which he described, as you say, as salesman's samples, but the labels looked wrong, the glass too thick, and some colours too bright. This made me suspicious, and when a small group turned up in a major decorative arts dealer's shop that purported to be surface decorated it confirmed my misgivings. They had an internal white layer that was thick and very opaque (not like the generally pearly white of true Monart) and the outer layer of brown was glossy, but not iridescent.
Too much of a co-incidence. Then your warnings went out through the Monart and Vasart Collector's Club
by a chap called...........Frank
I always thought that he was commissioning items up in Scotland, but your connections within the glass world, particularly Monart, were I suspect, more wide spread than mine at the time, so it could well have been somewhere in London. Better in some respect, since it was less likely that the maker would be aware of what he was involved in.
I do agree he did certainly go into the running for being the worst dealer in the UK, but I'm afraid there have been worse cases, which raised much greater sums for the cynical/greedy dealers that did the dirty!! Urgh
As a result of my experience at that time I always have an example of one of these fake
miniatures, with a fake label, on my stand to teach collectors so that they do not get duped. This sale high-lighted the need to keep on doing just that
