Well, I'll test several suggestions in couple of days. I've placed my max bid, plus I may increase it 1 to 2 days before bidding ends. I've put exactly how much I am willing to pay, and I'll add extra 100 bucks over - if the pen writes as I hope it does, I'll have years of joyful writing experience.
It is pricey, so If I lose then - someone really want's it and good luck to whoever the winner is.
Naturally, there is that "I must have this pen" ... the problem is - it is based on the perception - how a pen should write, in my mind. The reality is - only by trying a pen, I would know if that is really what I'm after.
Recently I've bought two vintage pens - both Waterman's. One is 52-1/2 V, near mint condition with flexible nib, the other one is ... well, it was advertised as 52 Red Ripple with flexible nib.
So - 52-1/2 V ... nice pen, I didn't have to have it, but it was "why not, the price is OK/low" decision, with hopes that flexible nib will write good. The nib is xxxxxxf and "flexible" is relative term. Perhaps it can flex to B but I wouldn't dare. It is also extremely sharp, rips the paper. Some work will have to be done on this.
The 52 Red Ripple - flexible, I got 54 with #2 flexible nib. Again, flexible is relative... not that flexible after all, from medium to broad and a half (maybe BB, but I won't test that).
All from a reputable seller. Have I had a chance to try them, I would decide in 3 minutes I don't need them. And that's the problem I have with eBay, and general online buying practice.
Looking at how much I've spent on pens this way, I would be better off just going to the pen show and try/buy on the spot.
