Thanks Ken! It is also very small.
Rotherham air pumpThe last days I had other things to do.
But most of the rigging is now installed, and I tried to add another detail: Rotherham air pump
There were different types, this one.

At the beginning I made a pump from brass. The pressure tubing is 0.2mm copper, the axle nickel silver.

My Sopwith Triplane built last year is not equipped with such pump, so I had still the Eduard PE. A bit flat, but I could use the mount frame.

I modified it a bit and added the PE parts and a real wooden prop.

The blades are very thin and the whole thing is very small!

Now it is mounted on a strut.

From another angle, and without airflow.

And here with airflow:

Another nice detail added

Cheers,
