A new sac was installed. It comes with a phenomenal 14k large conklin nib that writes with a f point and flexes to bbbb. Barrel imprints are almost completely worn.
One can still see the model number "40" towards the end of the barrel, but magnification and good lighting are needed. There is a crack above the clip (see photos). It will not affect the function. Gold-filled trim shows little wear on the clip.Length is just under 5 1/2 capped. While it has its issues, none is fatal. The nib compensates for its minuses.
