A 3A if I am not mistaken, the 3 had a similar nose cone to the 2 but with a grill....I rescued a 55 2 from a garden and it is to my shame that I never got round to restoring it before it was too far gone. I still have the original handbook for the two amongst my treasures..(-: I think the engine in your 3A us the same unit fitted in Mog +4`s of the same era..., and the rear suspension not a lot different..(-:
ENJOY.
