Hi guys,
With the wonderful and remarkably quick help i got identifying my Waterman Laureat, I thought I might try my luck in working out what my Sheaffer is as well.

It is stainless body and lid with Sheaffer U.S.A stamped on the lid. White dot on clip

Steel (??) nib with black plastic stamped M unfortunately cracked near joint

Serial number stamped on collar near the converter is 91664

Rather thin in diameter (5 or 6mm max) and approx 118mm (4 1/2 in)uncapped 135mm (5 1/4 in) capped.
