Westbury "Centaur" open crank engine

A 60cc open crank engine to Edgar Westbury's "Centaur" design, serialised in "Model Engineer Magazine" in 1957.

Turns over freely - the timing side mainshaft is extended compared to the original design and runs out slightly, although apparently not to the detriment of the camshaft skew gears.

Somebody has added a drip oiler for the piston, they've made a poor job of it, the oiler is mounted cock-eyed on the wrong part of the splash guard. Located an inch further back it would a) have stood up straight and, b) actually directed the oil where it needs to go. Not a difficult job to relocate, once painted it would be an invisible repair.
