The M415 Tortoiseshell Brown was a special edition M400 sold on the US market in 2009, it is made in older M400 style (without a ring at the filling knob). I bought this one second hand from Richard Binder and it arrived two days before Christmas 2010 (it was a great pen Christmas). This pen was my first Pelikan and rates as my favourite small pen. It is little, light, and quite simple in style and goes so well with my selection of M250 single tone Richard Binder custom ground nibs.
This old, tarnished, single tone 14K nib came with only Pelikan that is not in my current rotation, a pre-1997 Black/Green Striated M400. The pen has a leaky plunger and is on the list to be fixed. The nib while not much to look at writes without fault.
Blue Night is a blue/grey ink that was part of the Caran d'Ache Colours of the Earth series of inks that was discontinued in late 2012. These inks come in very heavy 30ml cubed glass bottle, made to look very nice on the desktop.
This ink is called Blue Night but its really a blue/grey, or is it a grey/blue. It shades very well even from the relatively fine nib. It is not the most exciting colour of ink that I own but does provide a point of difference from the blues, browns and blacks that populate my rotation of late.
