This is the second one, with the smaller exhaust and the wooden handles. This one has a steel roller drum. (The other one has an aluminium roller.) The engines in the two appear identical. The carbies are slightly different, but not much. They have similar magnetos, this one has the spark lead coming out on the top rear, while the other one has it coming out at the front and below the crank shaft height.

The only changes I have made to this is the braided fuel line, which I replaced. The original(?) was braided, but much finer.

Neither is restored. They are both as I got them in most respects. They have been cleaned up and some minor parts replaced or repaired. They are working mowers and I run one of them over the front lawn at least weekly. I have two catchers, and both are steel sheet construction. One has ATCO in an outline of the map of Australia, but almost faded completely away.

So many mowers, so little lawn.
