What have you done today with your Austin Seven
Needless to say you'll get a range of opinions....
I use 20W50 in the engine and a straight 30 grade in the gearbox. 
Some people favour straight 30 or 40 grades for the engine (30 for touring engines, 40 for sports) as originally specified - though if you go down this path I'd recommend careful warm-up as these oils flow less well at cold start, which is where all the wear happens.
Don't use heavy gear oils in the gearbox, the box was not designed for them and it won't penetrate where it is needed.
You don't need anything fancy!
