Are these old car models legit sets or MOCs? Are these 4 historic car models legit sets or MOCs? If official sets do you know the set numbers?

How can I add more pictures then one?
These are indeed legit sets of the 70's.

390-2: 1913 Cadillac

391-1: 1926 Renault

395-1: 1909 Rolls-Royce


Only the red car in the top right looks like a MOC version of the red Cadillac  set
