The Airmail pen company is well known in India and abroad and there are already several reviews about their pens on FPN and elsewhere.
They are known for making ED pens with transparent barrels. They also make Jumbo sized ED pens (6.3 inches approximately when closed, even longer if posted) in the series called 71 consisting of 71J(Jumbo marbled) and 7JT(Jumbo with transparent handturned barrel). Their new model in this series is called the 71JB (already reviewed by manojd) which was so far offered only in black acrylic with an engraved cap band and domed end jewels. They have now introduced this pen also in solid colors which this review will attempt to document. They call these as "English" colors since the colors are inspired from the colors of the english duofolds from the 50s.
The new colors: L-R: Black, Maroon, Blue, Grey.

The pens are fitted with the standard monotone yellow Airmail steel nibs, it seems the nibs on the 7JB have recd a little bit more attention, the pens have been good writers so far.
