I'm building the WnW DH.9a and have started with the Liberty engine. I removed the plastic between the cylinders which gives it a much better appearance. I also made and fitted 24 new spark plugs, fitted rubber hose connectors and hose clamps to the 12 pipes on the inlet manifold and made the propeller mounting assembly and fitted it to the drive shaft. I made 12 priming taps and fitted them to the inlet manifold, I also added the plumbing on the front of the engine using 0.25mm copper wire. These photos show the progress so far, still more work to be done.

Des.

Nicely Done Des. Looks like it just came out of the crate.
