Rare E. S. Johnson & Co. #10 Gold nib & black ebony wood holder fountain ink dip pen.  I personally have never before seen such a large nib.  This unmarked 14K gold nib measures 2-1/2 inches long and is attached, surrounds, NOT inserted into the pen body.  Total length of the pen is 7-5/8 inches long. 

Marked on nib E. S. Johnson & Co.; Warranted; New York; #10.  

Condition is very good pre-owned, used condition.  No attempt has been made to clean or remove ink residue.  As pictured, there are splits on back side of nib. There are professionals, not me, who could correct any slight flaws.  

Please check out all the pictures, as they are considered part of the description and contact me should you have any questions or request for more photos.  Thank you for looking!
