Yes if you post up the engine numbers...! but .020" should get you going.

If its been outside for 6 months in the UK then give the coil a good soak with WD40 and leave for a few hours, going by the photo's it could do with a clean up, make sure the breaker point plunger is moving, and that the magnets are good on the flywheel.

Start with a new set of points and condenser. They aren't that expensive and you will have less problems later on.
