If you look at his other items it seems that he is rather partial to using the Duraglit! For example, the Jersey 1/12 shilling he offers with a similar brassy shine and cheeky description.
Mind you we could forgive I suppose because in somewhat Pidgin English he does say, "We believe on Collecting valuable objects uniquely rewards me with beauty, history, personal satisfaction, and more. Honesty and fairness must define every facet of our life"!!!
...and we can further forgive a bit of polishing because, "Part of our sales goes to charity for Elderly People and Young Children"!
How pleasing it is to have such generous sellers on eBay!
