As soon as you have four pens....suggest nail EF and B and regular flex like a Pelikan 200/400 in M & F......Esterbrook made regular flex nibs.....other US pen companies also. Living in Germany never chased US pens the postage would have cost near as much as a pen.....as a 'noobie' I was into 'affordable' pens.
Sheaffer made regular flex, at least in it's sub brands.
So after four pens, it's time for semi-flex...........which is a flair pen.............Not A Flex pen. The bottom of the nib is stubbish.....flatish. Helps give line variation/flare with out you doing anything....no twisting of the hand, arm or hanging from the chandelier. That natural old fashioned fountain pen style....just writing regular.
Get your self a Geha 790 off of German Ebay....the seller needs to take Pay Pal and ship out of Germany .....many don't. Geha 790 is the Best Buy in semi-flex can be had with a little effort for @ E60-70....as long as you don't push the Buy Now Idior button. Then you can get over priced US prices....even in Germany. It don't cost nothing to wait for an idiot.
They stand in line to throw money away.
Pelikan 140/400 go for @ 100 is you hunt....a 400nn can be had for that too....but often for no reason go for @ 120.
If you wish you can pay E190 or even 280- Stateside prices.....no waiting...no thrill of winning or losing. Wear out your gold shovel as you throw money over your shoulder.
You want three rings.........the one with three true rings is a '59-60, the one other 'three' ring one is '60-72.
Original bought pen picture, the rings polished up just fine.
In the '50's the torpedo/cigar shaped pens were in...Swan, Pelikan 120/140/400nn, 146&49 MB and so on. Geha 790/760 and school pen..............the school pen has no rings but the clip ring and has a serial number engraved on it.....it is not semi-flex.
Picture to show the other three ring Geha 790.
I have three and the same size as the Pelikan 140, Geha 760, that cost normally 20% more than the 790....but it often come sin colors....a Golden Rule, any German pen but a Pelikan you will pay more if it is other than Black and Gold!!!
If you want to buy a oblique...................buy only a German pen made from 1950-70....it is semi-flex, stubbed and gives real good line variation.
Nails and regular flex don't....nails not at all, and regular flex a whisper of the real thing. They are really a waste of money.
I've had tow nail Obliques.....No line variation at all. The regular flex....have 4...and in OBB it is a whisper of the '50-60's OBB's or OBs.
I have a '90's so regular flex era Pelikan.....it was a real surprise to me to find out when looking at the nib after a long time in use....that it was OB..............I hadn't noticed it.
Semi-flex era only if you want the real thing.
And semi-flex straight nibs are a lot of fun too....don't have to be oblique ....have 29, 16 maxi-semi-flex ......and a mix of semi&maxi in my 16 obliques of that era.
Don't really count the other five in regular flex.
The nail obliques both Lamies, ,the Mdl 27 OM was sold and the other a 1990 Persona Pendelton Brown made it into a real nice Cursive Italic from OB....both had absolutely no line variation.
The Persona does now...........you can get any of your nail nibs made into a stub or CI.
The Persona has a spring loaded 'concealed' clip. Once it clips into a shirt it stays clipped to the end of the world............a real Art Deco influenced design.
