The Burnham 48, this model with a 'cowled clip,' was produced in the early 1950s.
Harry Burnham started the Burnham pen company, in England, around 1920 and it produced a great variety of fountain pens until it folded in the 1960s, partly because of the infamous 'ballpoint effect'.
The pen has been restored and tested. A new ink sac was fitted as the original had deteriorated with age. It is finished in an attractive marbled grey/ brown colour, originally with Gold plated trim. There are a couple of hairline cracks to the cap lip extending only to the cap band and this is reflected in the price. The Gold trim has not survived , it was never a thick Gold fill and it wears thin fairly quickly.
The nib is the original Burnham Gold plated B45 steel nib with a medium point. The Gold plating has worn and there is a small area of pitting.
