Wing Sung was the second major producer of pens in Shanghai, until their acquisition by the number one, Hero in the mid 90's. Several of their pens have become popular with collectors, and such was the size of their production that unused stock from that time is still available. Commonly known as new old stock "NOS", they are generally as good as new but may need a little polish and clean to remove tarnish and other signs of aging. It's also worth thoroughly flushing any NOS pen before it's first used, as it's probably been sitting in a warehouse for twenty years with the residue of whatever chemicals were used in its manufacturer coating its inside.
The Wing Sung 840 appears to be an imitation of the Sheaffer Crest. It's a very slim and quite light pen, with an attractive wrap around conical nib. The nib is two toned gold plated steel, the two Chinese characters printed on it represent the manufacturer, Wing Sung , The barrel is finished in a deep red lacquer which I love. The gold cap slips up flush against this and goes on with a very positive feel.
