Complete newbie here. Hoping someone can help me ID this pen I received in a lot on eBay. I am thinking perhaps a Parker, but the cap end and clip are missing. I want to replace these, it's a beautiful pen, but first I need to know what it is! Black with silver/copper Pearlized wave effect. Single band on cap - black tarnished with silver underneath. Window in section (yellow tint). Nib says "Curvex 14k gold plated", and I suspect could be a replacement. No other writing on the pen. Lever fill, but I have not been able to remove the section from the barrel yet. Sorry about the picture, it's the only one I have! Any help appreciated.
