From around 1970, this is the Mk2 version of the 51 aerometric series in burgundy with the Classic steel cap. This shows hardly any signs of having been used and is fitted with a fine oblique 14k gold nib - this is cut from top right to bottom left
This is a Parker 51 with the aerometric filling system. The pen fills from an ink bottle and does not take cartridges
Condition B/1f Oblique - (Ref 12464)
We have fully serviced this pen which includes disassembling the pen, ultrasonically cleaning all the parts and fitting a new pliglass ink sac. We then reassemble the pen, check ink flow and the smoothness of the nib. We also check and adjust the tightness and positioning of the clip.
This pen comes with our normal 12 month warranty. We keep a detailed record of each customer's purchases so if you need to call us, we will have all the information here to answer any query
Differences between the Mk1, 2 and 3 are outlined in Shepherd's 2004 book on the Parker 51. We usually follow his classification of the principal 51 design changes which generally agrees with Andy Lambrou's description in Fountain Pens of the World (1995). The Mk2 is of similar quality to the Mk1 in terms of the materials, but features a cap design similar to the Parker 61, a squared off end to the barrel and a slightly longer nib shell. Barrel threading on the Mk2 is the same as the late Mk1. The English production Mk2 came in black, grey, burgundy and teal blue with either the Custom (rolled gold) or Classic (steel) cap. Mk1 and Mk2 nibs are identical.
