A Bowman Models Electrical Dynamo, Model 839.

The dynamo has a back horse-shoe-shaped magnet mounted vertically around a horizontal wound armature. On one side of the shaft there is a small drive pulley with a knurled groove, reminiscent of the knurled pulleys used on the Bowman range of Aeroboat rubber-band driven boats (to allow them to be wound with a loop of cord).

At the other side is a vertically mounted lightbulb holder (the bulb is missing).

The square base is a classic Bowman design, red-painted folded steel with a raised central area and a row of six Meccano-spaced holes along each of the four sides.

A tiny plaque (not present in the catalogue illustration) says "2V 0.1A".
