What Ho! I have a unique banjo for sale, made as a 1 off in an Uncatalogued WF colour.
It has excellent provenance as comes from an ex-Whitefriars worker. This banjo was looked at by 2 eminent ex-Whitefriars employees at the last Cambridge Glass fair and concluded that its was made from either glass from the stained glass dept or from a paperweight cane pot.
It is in superb condition with no damage. There is a slight opaque streak near the ground pontil where an impurity has come off the iron. There is a few bubbles and odd bits of frit in the glass but this is all quite normal.
I have photo'd it next to a Tangerine brick for comparison.http://i42.tinypic.com/xbwmdg.jpg
If you are serious Banjo collector this will be your only chance to purchase one like this and as you would expect it wont be cheap.
If you are interested contact my email email@example.com
I am well known around glass circles, kind regards Wolfie
