Aiken Lambert, made about 1908-1910.
An unusual and highly desirable gold-filled full overlay in the cable twist pattern. This is a larger than average pen, with it's original #4 nib and feed. There is no brassing, and only extremely minor dings. In overall excellent condition, and a fantastic writer. The hard rubber is crisp and black with no oxidation at all. Notice especially the scroll work at the end of the cap. A very nice pen.
