Interesting discussion. It is not my understanding that Parker has stopped warranty repairs but I wouldn't need Parker to repair a pen for me. Do we know what was wrong with the pen? Broken mechanism, missing part, sprung clip, cracked barrel, etc. I can certainly believe parts are not available and right now I can believe Parker isn't repairing anything because Parker is likely closed for all repair work due to COVID19.
A few thoughts on this. Parker (or any manufacturer) can not keep a parts supply for old models indefinitely. Laminated Celluloid in the Vacumatic series hasn't been available for something like 7 decades. Even during the 51 product run at one point Dove Gray Lucite became unavailable and Parker substituted Navy Grey and that was while the 51 was still in production. Speaking of parts, I'm confident I can name 10 people that have more parts supply for 51s, original Duofolds, 75s, or Vacumatics than Parker has.
When it comes to repairing the modern Duofolds many of the materials especially from the early runs are no longer available so Parker couldn't even make the parts if necessary. Predicting what parts may fail isn't always easy. Duofolds have a habit of the cap lips breaking due to dropping and over zealous posting. The configuration of the caps has changed from year to year and when the parts are gone they are gone.
I don't believe the story about the Queen but am open to more information on when this happened and documentation that it did indeed occur.
Lets try and help the OP's friend that has a broken pen. What pen is it and what is broken. Some basic details would certainly help further the understanding. If nothing else, I'll contact Parker and find out what is going on.
Enjoy your pens.
There are more than a few sources for original parts and repairs to vintage and even modern pens. Many of those sources post here and/or monitor such threads. I'm confident that manufacturers know what is and isn't going on
Thank you for your thoughts FB.
I cannot speak for others but my thinking is not 'can they' but 'should they'.
You are not the average Parker buyer in that you have special skills when it comes to pen maintenance, probably better than most Parker employees.
A typical owner of a Duoflod may have been given a $500 pen, 18 months into ownership the pen is dropped, the cap is broken, the pen is taken to Parker who say, 'the pen is out of Warranty and accidental breakage would not be a Warranty item anyway, we don't repair it.'
The pen means something to the owner and now has very limited choices, replacing the cap will be difficult, repair of the cap doesn't look possible and who would do it anyway, the best placed people to do a repair have just said get lost.
You can imagine that the owner may be thinking, $500 spent on this pen and now it is useless, one of the best known and trusted brands and they treat their customers this way. The owner does not want a discount voucher, the owner wants their own pen because it was a gift and it means something, and if this is the way they treat their customers the they would not be buying another Parker.
Agree your point on parts availability, no one can expect NOS plastics to remain on the parts shelf for 70 years, that would be unreasonable, however I would expect a manufacturer such as Parker to keep a stock of parts for the more expensive current production models, especially Sonnet and Duofold.
This is the trouble when you allow accountants to run companies, there is more to running a 120+ year old business than figures on a balance sheet.
