The fountain pen is 141 mm (5 9/16 in) long when capped and 173 mm (6 13/16 in) when posted. It is a slender ED, with a diameter of only 8 mm, and it weighs no more than 8 gr. For sure, it is a delicate pen. The cap is 60 mm long and has four vent holes (two pairs of two antipodal holes).
The ED has an uncommon but characteristically Aikin-Lambert & Co (acc. to David Nishimura) extra fine #1 nib with a round hole not connected to the slit, medium flex. The feed is a narrow keel-shaped one.
For the above pictures, I used a vintage post envelope illustrated with the drawing of the building from Manhattan where the famous jewellers had their shop in the era.
