The Conklin All American is an excellent pen,
it writes beautifully, starts right away and does not skip. The medium nib is smooth with plenty of ink flow. The line it puts down is not a generous medium, but is more than adequate.
The pen is absolutely beautiful and a pleasure to write with.
Conklin fountain pen
This pen is a dream to write with. It looks exactly like a vintage model (though I can't find any info on the '30s version of the all American) and writes really well. It's an eye catcher, comfortable to hold and is very well balanced. Though if you have thick fingers, I recommend caution because this pen has girth- about as thick as a ring finger and MIGHT be awkward to grip, but all in all, a very affordable and good pen.
