This car was offered for sale by the Italian Classic Car dealer Luzzago a few years ago, when it was described as
a Fiat 1100E chassis (see the number), with a 4-speed gearbox from a 1962 Fiat 1500/Osca, new Borrani wheels from a Maserati A6GCS, and custom brakes Fiat 508C derived. It had no documents. The car was built in the 1980's as a recreation by Giordanengo, with an aluminium body similar to a Ferrari 375MM by Pininfarina.
The only Lancia part in the car is the engine, which is indeed from an Aurelia, probably a saloon, but I would need the actual number to be certain.
Buy the way, the car is offered at the Karl Ritter Collection in Austria.
