A titanium Kaweco Sport (not Majohn’s take). It’s a grail because it doesn’t exist yet, but I’m not giving up hope.
Realistically speaking, a CAISO Conid Kingsize demonstrator and a Conid Regular R DCB DB FT TI model are the two grails.
My personal grail is a Richard Mille RMS05 https://www.richardmille.com/collections/mechanical-fountain-pen
Visconti Homo Sapiens Bronze Age. I really like the look of that pen but I will admit to some serious reservations regarding their nib QC. I don’t expect to pay out that much for a pen and then have to send it to a nibmeister to get it to write properly. It is all dreaming anyway. No way I can spend that on a pen any time soon and I’ve more than enough of my own pens to rediscover.
I am happy to say that I have none now. Not that I have gotten all the pens I fell in love with but I am happy with my 2023 purchase. Maybe as 2024 rolls around I may reopen the conversation with myself again.
@hsl@wayfarershaven.eu If you mean pen I aspire to but can’t afford, it would be the Pelikan M900 Toledo, because it’s so beautiful.
