Thank you! I'm really unsure as to whether it's plated or filled, I've heard/read both. I don't have any way of knowing, other from someone that *really knows*. I believe it's plated, as this is the best information I've been able to find, from parkerpens.net: "In 1906... ...Another new addition was the #35. It was a heavy 18k gold plated overlay pen with a floral design and a name plate...".
As for comfort, I haven't really experimented with it, since it currently lacks a functional nib. I'm just super excited about it, because when I bought it, I knew I had found quite a prize. My heart just about leapt out of my chest when I started researching it and saw how much the ribbon pens go for! My wife immediately took it and put it in the fire safe, which is funny, because she was trying to disuade me from getting it! Robert at Five Star Pens said an offer of $3,500 would be reasonable but not to expect to get more than $6,000, if I decided to sell it. I really just want to hear from some other folks in the community, to know what I really have. If it's valuable enough, I'll be willing to part with it so my wife and I can make a down payment on a house. I'd like to get a nib for it and sign a few checks first, though...
Admittedly, this is my first fountain pen, though not my first Parker. I also have a Flighter GT from 1990 -a nice, functional pen but can't hold a candle to this beauty! Honestly, I'm kind of afraid to use old "Glennie Biggs" as just the correct nibs are $100-$200 a piece -at least the only ones I've been able to find. I'm still not sure exactly what kind of nib it takes, either. I certainly don't what to put something in her that doesn't belong there!!! I've always liked fountain pens and never had one. I couldn't justify buying one until this one turned up in a thrift store for essentially $3 (it was in a set of 5 similar items for $15). Now that I have one, it's turned out to be probably the most exciting purchase I've ever made!
