Mystery steam engine

[chris123]

I am looking at the relative positions of reversing handwheel shaft that runs across on end of the engine and the weighshaft that runs down the side and moves the reversing gear. If there was a lever on the end of the weighshaft then I would expect the revesing shaft to have been threaded. As it is not, I think perhaps it should have a worm and sector arrangement.

It also seems to be missing the 'lifting links' from the weighshaft to the pins on the ends of the curved 'expansion links'.

Thank you charles

No idea who designed or made it, but it has some high-end features. How big is it?
