I bought it at least 3rd-hand, it may have been more, from an FPN member. It, the 'Amber'* version, arrived as well as, if not better than, described. A fair buy at $375 (including delivery to a hotel in another US state, from which a fellow British member of a watch website brought it to England to post to me). Anyway, the US seller was first class, taking a lot of care with the sale.
Slow to fill with the vintage 'Vacumatic' mechanism, the limited edition of 113 (in Amber) pen worried me a bit at first. Indeed, I wasn't sure the thing was filling at all. Pump, pump, pump, against little resistance, seemed to put little ink into the barrel. Finally, however, it seemed alright, if not full. The ink was Diamine Ultra Green.
Then the Stub nib went to paper and the result was ... well, not quite as good as my Visconti, but very good. Indeed, so good that I have just spent $150 buying another 'Bexley' (aka Bock) Stub nib for a Mercury I have. (If it's as good as the first, I may well buy another for another Mercury.)
The Bexley-Diamine Ultra Green combination is a very good one. A well saturated, unproblematic line, that was immediately usable and is becoming even more so. The double-glazed window helps, because it really is usable, too, as is the rolling-ball clip.
So, a good pen? Yep. Now, my daily user. I should admit, however, that I bought it only for its *'Havana Blue' Tibaldi celluloid. Lucky, lucky, I received much more than I bargained for.
