Back in the 1960s, there were several companies producing kits to make the static Kitmaster and Airfix model railway plastic kits move.
In my collection, I have this little mechanism part fitted to an Airfix Pug. Bought second hand, there are no instructions or other way of identifying it. I don't think it's likely to be scratchbuilt as the Mazak bits underneath are cast. The con rods also look like they are stamped rather than fettled from metal too. Nothing is provided for the cylinder rods by the way, I assume you use the plastic parts for this.
So, I throw the question out to the crowd, who made this mechanism?
