The PMR vertical is quite nice or the GLR kits are popular, you can get them in various states of build to suite what you feel able to do yourself. They are a decent size and should cope with your No 3 and future engines.

They are indeed; and I note that [to a first approximation], they all have the same straight-line slope.
I don't know if there is a standard unit for this, but; it should therefore be possible to state the "performance" by the value of that slope, and its height on the graph.

I was at a local show and there a few small model engines on a table, wobbler small stationary engine etc. they were running as I had a look at them. The chap in charge had a foot pump under table and just pumped when needed.

We are an odd bunch, don't you think?
Someone goes to a lot of trouble making steam (or water*) drive a motor driving a generator, and this makes electricity. So what do we do? - we use the electricity to drive a motor to produce compressed air to drive a motor. And then some of us use the motor to drive a generator ...
* added so that our Swiss and Norwegian colleagues don't feel left out.
