Vintage 1970s Parker 'Flighter 25' Fountain Pen in Brushed Steel with flat top and blue trim. 
The Parker pen specially designed at Newhaven to handle air travel, made to be robust and sturdy - virtually indestructible, the body being made with a 'deep draw' press. Easily replaced steel nib. A good writer.
Comes with cartridge converter suction ink bladder (for bottled liquid ink) and 3 optional full ink cartridges 
Excellent condition as can be seen
