Dear friends,

i have a question, i have got a Parker 51 pen, in a mint condition which was belonging to one person and was never through maintainance and the nib hence was never replaced.

 

the nib is gold in color, it says:

Parker

Made in USA

R U

 

 

i want to know what the RU stands for?

i have read on one site the following:

"Tipping on the Parker 51 with its nib marked RU is applied as a pellet. Because pelletized metal do not occurs in nature, we can surmise that this was refined, alloyed, and turned into a form that could easily be used in manufacturing. (An awareness of osmium as a dangerous biologically reactive substance occurred around this time and may explain its absence. Osmium oxide’s toxicity was well documented by 1940.)

Ruthenium - 96.2%

Iridium - 3.8%"

:

is that correct?

and whats the rarity of this kind of nibs?

Thanks alot!

No more rare than any other 51 nib.

Almost all Parker 51 nibs roughly from 1947 until 1950 were marked, for the tipping material, as RU. There were nibs prior to that that carried the marking OS-PL (Osmiridium Plathinium) and RU-PL (Ruthenium Plathinium).

 

Later nibs were marked as PU.

Interesting... RU is the correct abbreviation for ruthenium, but the correct abbreviation for platinum is PT. Why would Parker make this error?

For love of it. And yet not waste time either.

That means that they don't have any gold?

The gold color Parker 51 nibs were 14k gold even if these were not marked so.

Plathinium and not Platinium.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
