Brown Junior CO2 Motor

My friend Bruce has just been given this co2 motor, It looks like its brand new and never been run. Does anyone know the history of these motors and how old they are. Wow it's really small. I have owned a couple of co2s but nothing this small.

Colin,
Information from the American Model Engine Encyclopedia:
There were two production runs of the Brown Campus A-23, one in 1981 and the second in 1982. Both were .23 cu.mm. or .0014 cu.in.. Black steel cylinders on both with sand cast aluminium crankcase on both. The 1981 engines had a plastic piston and the 1982 a steel piston. 1981 tanks had a magnesim tanks top, aluminium tubing and filller valve.The 1982 version had copper tubing and brass tank top and filler valve. Some history here:http://www.craftsmanshipmuseum.com/BrownJr.htm
Hope this helps you

W.
