Definitely a Belna NOT an Augusta. Non standard steering wheel cannt tell if all the instruments are correct, finding hub caps could be difficult, shame about the tear in the headlining but a very good basis to start a sympathtic refurbishment.
Italians seen to ask E35,000 for restored Augustas, but they dont seem to sell
A very good part restored Augusta has been for sale for a long time in UK for £18000.
Its got to be worth several thousand £.
Don
This one I take it....
