Working, smooth writing, vintage, green pearl Esterbrook fountain pen with a #2668 - firm medium nib. Double jewel but the cap jewel is incomplete -- see pictures. Lever-fill. Recently re-sacced and then inked & used. The writing example shown was done with this pen. I believe this is the Esterbrook "J" style. 4-7/8" long when capped. Sold in used, previously inked, condition.
