1942 third quarter Blue Parker Striped Duofold.
The pen performs is a very nice writer, one that I used personally for a while.
I would definitely say that it is in user-grade condition.
The cap band is brassed and loose, and the clip is brassed as well. The barrel is transparent, but it is well ambered. The bling cap threads are a bit worn, and it will snap if you tighten down the bling cap too much.
None of these things are really as bad as they sound, but I believe in full disclosure.
I have fully gone through the pen and it has a new diaphragm and is ready to use and a knockabout pen. One that you can use and abuse and not have to worry about messing it up, while still having the pleasure of writing with a 72 year old pen.
