Un-finished piston valve steam engine parts
 

I picked up these parts a few years ago and won't get around to using them. It was a deceased estate so I didn't get the full story. I think the bloke was in S.P.U.D.S (an early steam group based in Sydney that promoted the use of steam in everyday life) and these castings were to make car engines, I assume around the 1960's.

The 3 machined cylinders look to be meant to go together. There are no pistons (2.5" bore), piston rods, piston valves and whatever else you can see that is missing. A lot of work has gone into making them. An interesting project for someone.

Then there are some other un-machined castings with different cylinders sizes and styles. One casting at 4.5" bore, two at 3ish".

An offer for the lot. Who out there in Australia would like to make these into something?
