Plus 1 for Diplomat. I got rid of a light metal C/C Diplomat, that was a nail, it had real good balance. I often regret selling that pen.
A few months ago, my wife found a dark Maltese Cross Diplomat at a German flea market, , Maltese Cross in the Finial (WOG early-mid '50's similar shape to Soennecken or Original Reform), on the clip, the cap band, and Maltese Cross just before Diplomat on the side. Steel nib (gold wash or plating gone), maxi-semi-flex, Maltese Cross on the nib too. Don't know what the 20 on the body means. (blind cap)
Thinner, a touch longer than a 200/400 not quite as long as a 600. Wrote down the pen in my card box....forgot to say what brand of purple ink I used.... suspect & now DA Aubergine.
The one below with the gold colored stirrup clip and trim is actually in silver plate but when I buy a pen, I steal the photo. Wife's pen she will never use..........there is a tennis one too. Is regular flex.
German vintage '50-70 semi-flex stubs and those in oblique give the real thing in On Demand line variation. Modern Oblique is a waste of money for a shadow of line variation. Being too lazy to Hunt for affordable vintage oblique pens, lets you 'hunt' for line variation instead of having it.
