7150: Bolles Standard: smooth black hard rubber screw-cap patent self-filler, 14.8 cm long, made in Toledo, Ohio; correct #2 Standard nib missing iridium on one side.

6168: Laughlin doctor's pen: black chased hard rubber eyedropper-filler, thermometer in compartment at end of barrel; 16.3 cm long, crisp and glossy, new old stock, never filled; came to us without a nib -- we have fitted it with a Laughlin nib of the correct size and era, which does however have an axial hairline crack from the vent hole; an outstanding example of a very rare design.
