I went for a wander into one of our local fleamarkets yesterday and am very glad I did; I found a couple of very nice bargains. Apart from a surprising Senator Steno (posted in the German regional forum) with a fabulous fine flex nib (£5), I came across this Platignum Pressmatic "M" in great condition with it's iridium-tipped 14CT gold riband it's original case for a meagre £4 (about US$6, I think). It writes very smoothly and I'm very happy with it.
Although the reputation of Platignum may still be far from the Parkers and Shaeffers of the same era, this pen has a really very nice nib and has quite a stylish look, with the cap jewel matching the barrel, and the barrel jewel matching the cap. It really doesn't feel or look like the cheap brand we think of when we think of 1960s/70s Platignum.
Anyway, I was so chuffed with picking these up for such a bargain price, I had to share!
