The car is a 1930 Rolland-Pilain Grand Prix car which was up for auction last year. According to the auction information, it has an all aluminum body, and is powered by a Continental Red Seal straight eight.
Another one solved by the experience of the Pros. The point is yours.
There was no Rolland-Pilain GP car of that year. I have no information about what the chassis really consists of, but the marque did install Continental/Lycoming engines in that period. The car was for sale in Argentina, and I guess that that's where this speedster body originated. These American engines were first fitted from 1930, so that tallies, but the last GP cars from R-P were built in 1923, and this chassis looks bigger than those.
