Parkers:

P1. Parker Duofold Pen with "Y" code - about 29mm, semi-flex, fine point, tipping intact, may need a touch of smoothing, but doesn't feel bad, looks like it has been well used and tweaked a few times - $35

P3. Parker Lucky Curve Pen #2 - about 24mm long, fine-med, very flexible, fairly smooth but might need some tweaking once on pen, dents and damage to heel of nib as seen in picture. $25
Waterman:

WM1. "Waterman's Ideal New York #6" - 30mm long, pretty firm with no real flex, fine-medium point, smooth, a few light scratches on the top, but otherwise fine. A very nice example of a hard to find nib - $85.00
WM2. "Waterman's Ideal 14K Reg. US Pat. Off." keyhole nib, #5 size, but not numbered - about 29mm, fine point, semi-flex to full-flex, really nice condition. I used this one on a frankenpen for a while - it is a really nice writer - $55 (note - I also have a red-striped Waterman feed that went with this originally).

WM4. Sold/Traded
WM5. "Waterman Ideal 14K Reg. US Pat. Off." #2 "Account" nib - firm, extra fine point, smooth, overall very good condition. $25.

Terms - first clear "I want it" pm or email gets it. Reasonable offers considered, but full-price offers get priority over other offers up until we make a deal. Paypal preferred but MO in US funds OK.
I am not actively soliciting trades at this time, but will always trade for Baird-North pens and might consider Charles Ingersoll (especially bakelite), Good Service, Diamond Medal, Webster, Tower, Trupoint and Sears brands. Also looking for an Eagle Shield nib and an ALCO nib.
Also please note that I am best at returning messages during the week. I sometimes get very limited time on-line during the weekend, so if I do not get back right away that is why. Be patient and I will get back to you!
