I recently bought a Platignum for similar nostalgia-based reasons.What a seductive thread.
I've had many pens over the years, but fondly remember the Osmoroid that I used at school...
My Lamy Safari arrived today. Just been writing with it (just got blue-black cartridges for the moment, but I'm planning which bottled inks I want to try), and it seems to write really smoothly. It's a fine nib, and tbh I don't think I'd want to go any finer (they say Lamy nibs run a bit broad - but this seems as I'd have expected for fine). It works like a dream in my Moleskine cahier (despite warnings among FP aficionados that moleskines aren't that good for FPs).
It writes even smoother when I've posted the cap, which I wasn't expecting. I guess it's the added weight, or the subtle change to the way I hold it, maybe?
So far, so good.
Now I want to track down a Parker 51
My new pen is a Sailor ProColour - it has an insanely fine nib, as I'm told many Japanese pens do, but writes very smoothly indeed, though I imagine the sharpness would mess up any sort of rough paper.
Sparrow: the 1.1 italic is really quite fat. Unless you have huge handwriting I don't think it would be a good standard writing nib.

Also the J Herbin Rouge Caroubier is a nice bright red ink, not really for standard use but I was looking for something to use for editing.
I used to have a Rotring, about 25 years ago, and used it to do a design on glass over paint, which completely ruined it. I was so stupid. The best pen I've ever had.I've got a Rotring Newton, which is the business - love writing with it.
