Here is a beautiful example of a 100-year-old plus conklin crescent 30p in black chased hard rubber. It was disassembled and cleaned. A new sac was installed.
It comes with an excellent 14k conklin nr. 3 nib that writes with a b line and has full flex. The gold-filled clip shows some wear on the shoulder and "cap".
The color is excellent, 9/10. Beautiful example and a capable, wet nib.
