Starting a '48 Bentley

Hello all,
My dad has a '48 Bentley mark VI that hasn't run in years. I'd like to get
it going again.
1) How do you set the mixture and advance controls on the steering wheel hub
for starting?
2) Aside from the usual precautions, drain and replace gas and oil,
top-lubricate the pistons and crank the engine, plugs out until oil pressure
comes up, what other measures should I take with an old huge in-line six?

Thanks in advance
