Mark posted what I think were these photos in 2013 when much of a Re.2000 was recovered from the sea and placed in bath.

Could the trailer be connected with the following?

The Regia Marina (Italian Navy), however, experimented with a carrier version (Serie II) which was successfully launched by catapult. Lacking a carrier, Italy used a similar system to the British CAM ships equipped with Hurricanes. The first proposal was made in late December 1940, although the program officially began with an order issued in April 1943. The first modified Re.2000 Cat. (taken from the Swedish orders) flew on 27 June 1941, the last on 18 January 1942 (MM.8282-8288), but crashed on 10 September. There was another navalized Re.2000, the MM.471. It flew initially with a lower powered A.74 RC.38 engine, but it was lost too, during the travel from Reggio Emilia to Taranto (12 May 1941). The first launch was performed on 9 May 1942 with test pilot Giulio Reiner.[11] The work to make suitable the Re.2000 Cat., nicknamed Ochetta (little goose) took considerable time and only at the beginning of 1943 were they used aboard the Littorio class, but not more than one for every ship (although capable of holding three aircraft). Initially the Re.2000 Cat. aircraft were issued to Littorio and Vittorio Veneto, while Roma followed only in the summer, after testing had taken place aboard the RN Miraglia.

What does it do to a radial to be tipped like that?
