Montblanc Schering promotional doctor's fountain pen, propelling pencil and thermometer set

This collectible set from the 1930s consists of three promotional items manufactured for the German pharmaceutical firm Schering. The set includes a button-filler fountain pen, a matching propelling pencil, and a cased thermometer.

All three pieces are finished in black hard rubber and feature the Schering brand name engraved in gilt script. The fountain pen, believed to be a variation of the Montblanc No. 25, measures 128mm in length and is equipped with a gold-plated teardrop-shaped pocket clip and a 14K gold circle-vent nib with medium flexibility. It features a characteristic domed cap top design. The matching propelling pencil measures 131mm in length.

The accompanying thermometer is 100mm long and is housed in a 107mm protective case. These items served as corporate promotional goods for the medical industry during the early 20th century, combining high-quality German manufacturing by Montblanc with professional pharmaceutical branding. The pen and pencil represent typical writing instrument styles of the late 1920s to early 1930s period.
