Great find!  When do you start the model?   

[Michael S.]

Yes, I would like to build it, but I don't know when I'll do it yet.
There are so many other projects.
Finally, two more pictures of the engine when it came to me.

Amazing restoration!

[Charles Lamont]

Great restoration. I am surprised the lugs on the cylinder casting survived the bending of the support columns. I would call that Marshall valve gear. Hackworth has a slide and die-block, while Marshall* uses a swinging link, which makes for a more durable and quieter gear.

*There are other Marshall valve gears and quite a bit of confusion around them. One was used on later Marshall traction engines and does have a big cylindrical die block that the eccentric rod passes through.
