Excellent pictures, Parmigiano!
Secondo Campini was perfectly aware about the advantages of a turbine linked to a compressor, but he could not be faithful in this system because no engineer could really in the thirties!The first British and German gas turbines had a very bad efficiency and the first efficient ones had very high fuel consumption and a low reliability .
Campini realized that the best way to move a compressor would have been an alternative engine if you can't build a gas turbine that whitstands to thermal and chemical-oxidative stress from the combustion.
British Empire and third Reich themselves had troubles with their gas turbines, but Italy neither had their good metallurgy, for the lacking of chrome and nickel for a fireproof steel alloy.
But the most important innovation of CC1 was the after-burner idea: it had the first after-burner of the aviation history!
It didn't performed well also for the cooling troubles of its Isotta Fraschini engine but an aircraft with a conventional propeller would have suffered its same troubles.
Motorjet had not a future, but it was considered in 1930-40 the most efficient system for speeds up to 700-740 Km/h in particular for long range flights.
This idea was followed by USA ( "Jeep" project by NACA) and by Germany ( Heinkel and Junkers motorjet projects) up to 1942-43.
