Stuart Models Beam Engine - part machined for completion

Please review the photos to see what items are present - key fiddly items such as the linkage for the watts motion and valve gear operation are present. There are some parts missing, for example the pins that go through the main beam to hold the watts motion and con-rod in place don't look like the are there, you must assume that some other parts are missing. There are some duplicates, for example the main bearings and the beam column.

Some of the parts may be from a set of machined castings from Stuart Models, these components were stored in two Stuart Models boxes, one with the item code for un-machined castings and the other one for machined castings. For example, the watts motion and valve linkages look like they might be laser cut which isn't how the un-machined casting set is supplied.
