Unusual Oscillating Cylinder Locomotive

Thought you chaps would be interested in this. It was acquired by a friend:- Its a four cylinder oscillating locomotive it cam complete with a vertical steel boiler not sure if the cylinders are compounded or not.

A little bit of clearance never got in the way

Hi Stew.

I know nothing about this engine but my initial thought is that the builder has utilised the castings (fabricated component?)  that would normally have been a cylinder / valve chest and made valve bore operate as a second cylinder  :headscratch:

I can't see how it could operate as a compound unless the low pressure cylinder had a separate valve independent of the rocking motion as at the moment the 2 cylinders are permanently in phase with each other.

It would be interesting to see how the cylinder / portface is machined / drilled, that would tell us a lot  :)
