The Parker 51 Custom was an upgrade to the 51 Classic in that it had a 1/10th by weight 12 Ct. rolled gold cap, whereas the classic came with a 'Lustralloy', or steel cap.
This is a superb example of the Parker 51 Custom, made in in the early 1950s. It is
finished in Teal, named after the wing flash on the duck of that name. It is a very attractive blue/green with a 12 Ct. rolled gold cap and is in perfect condition, I doubt that it has ever been used. It shows no usage or handling marks, has an unstained ink sac and is presented in the original 'mock croc' box, also pristine and correct for this pen.
there is nothing much more to say about the condition of this pen, I'll let the 16 photographs speak for it.
The 51 is the first choice of many collectors as a daily user, it is totally reliable, stylish and very practical with a great deal of prestige. The 'as new' condition of this pen makes it really something rather special.
