3 inch scale dynamo

A large model dynamo of vintage style and proportions, suitable for a 3 inch scale Showmans engine or similar.

We motored it up in the lathe, recording the following voltages:

RPM	volts
150	1.1
300	2.2
600	4.5
800	6.0
1000	7.5

In good mechanical and cosmetic condition, it appears to have had little use.

Includes free UK shipping.
