Very cool.
And yes, probably Cross or Parker. Both make excellent long-wearing pens.
It is a heavy pen! I just found it a couple of weeks ago sorting out boxed stuff I had in storage. The stories I could tell about that trip, especially after my director arrived the final week. I worked my ass off until he arrived, then he dragged me out every night that last week, I spent all of my accrued per diem monies I'd tried to save attempting to match him buying pitchers of beer. The last night before he flew out we got especially trashed and my director had to sit with VP Cassidy on the fly back the next morning (Changi Airport to San Fran) while hung over! Lol! Cassidy didn't drink IIRC. My director probably reeked of beer. Apparently all was good.
