Beautiful piece of engineering. Presumably from Allenheads Mine ? Do you know anything further about it ?
Yeh, I used to rent the wokshop that was its original home.
There were 3 (poss 4) at Allenheads, this one was in the top mine yard and powered the sawmill (timber building still there) via a lineshaft under the yard. The rest where underground and used for pumping.
Helped out a little with the repair to the cracked cylinder and fiddled with the engine on the odd occasion, it runs remarkably smoothly.
Sadly the water supply comes from one of the dams owned by the Beaumonts, and the estate don't want it run because of the amount of water it consumes (the dam is stocked with fish)
The repair isn't very pretty but it works and doesn't affect the original parts off the engine at all, its simply clamped around the cylinder.
Nest time I'm back up in the neighbourhood I should really get a video of it running.
