Is it my poor eyesight or is one track on backwards from the other? It actually looks like a very restorable Cat. It has the side curtains and the seat looks very straight. Radiator looks OK. Fixing the engine might take time to locate parts but there is a good beginning to saving an old Cat. Grant.
Grant, your eyesight is still good. The right track is on the wrong way.
To me it looks like there is too much track adjustment already (picture 17).
Also to me the right sprocket (picture 16) appears damaged where the bushings ride but it may be the camera picture angle or some other reason.

Those rails are wooped! All stretched out, look at distance on the links.
