Obviously we need a separate Caproni Vizzola designation list.
I'm postulating that an almost uninterrupted numerical sequence can be made of Caproni Vizzola designations (until the gap between the C-22J and the 'zwilling' A41). However, even if true, there is one anomoly -- the Caproni Vizzola MF.
[
Update: Hesham's C.V.7 shows that a sequences
cannot be made with Caproni Vizzola designations.]
The MF is listed by j2mcl Planeurs (
http://www.j2mcl-planeurs.net/) as a single-seat training glider with a 14 metre span. Only 1 MF was built in 1938. The MF is attributed to Caproni Vizzola & Gruppo Tommaso dal Molin. Design was by Carlo Ferrarin and Livio Sonzio (who also designed the C.V. 1° and C.V. 2° sailplanes).
There is also a cryptic mention in Golden Wings of a "Vizzola glider" (I-ABNY at Varese 30.04.40). So, was this MF glider registered at I-ANBY (or was that reg for the C.V. 1° or one of the four unaccounted-for C.V. 2°s)? Alternatively, was MF an alternative designation for either the C.V. 1° or C.V. 2°?
Then there are questions of Caproni Vizzola designation style. Why was Caproni Vizzola the sole Caproni company not required to use 3-digit designations? And what did the prefix letters stand for? Here is a guess:
C.V. - Obvious stood simply for
Caproni
Vizzola
A -- Probably just stood for
alianti (glider)
F - Stood for designer,
ing. Fabrizio Fabrizi
C - Stood for
Caproni (Caproni Vizzola being the sole survivor)

C.V.2 - single-seat parasol sailplane with canopy, 14 m span, 6 built, 1938-
- C.V.1: Usually referred to simply as the Caproni Vizzola 2°, (c/n 2-6)
-- Caproni Vizzola 2°: c/n 2 (I-ABKX), c/n 3 (I-RENI)
C.V.3 - (Project) single-seat biplane aerobatic trainer; spatted main u/c
- C.V.3 : 1 x Isotta Fraschini

C.V.4 - (Project) 1940 single-seat monoplane fighter aircraft
- C.V.4 : Low-winged monoplane with retractable main u/c
- C.V.4 : 1 x 1,175 hp Daimler Benz DB 601A IV-12; span (??)
-- C.V.4 design is almost certainly related to Fabrizi's F.4 fighter
-- Previously reported with 350 hp IF
Gamma as fighter-trainer*
-- * If at all accurate; parallel to later F.5
Gamma development
C.V.5 - (Project) biplane aerobatic trainer; enlarged C.V.3/C.V.7
- C.V.5 : Few details but approximately 130% the size of C.V.7
- C.V.5 : 1 x (??) hp (??) inline engine;* span 10.00 m
-- * Being larger than the C.V.7, possibly an IF
Gamma IV-12?

C.V.6 - (Project) 1940 2-seat, twin-engined monoplane fighter; twin tails
- C.V.6 : Close-coupled back-to-back crew; leading edge radiator intakes
- C.V.6 : 2 x 1,175 hp Daimler Benz DB 601A IV-12s;* span (??) m
-- * Presumably Alfa Romeo R.A.1000 R.C.44 intended for prod'n type
C.V.7 - (Project) 1940 2-seat biplane trainer; single- or 2-seat vers. studied
- C.V.7 : 1 x 300 hp Isotta Fraschini
Beta R.C.10-I; span 7.70 m
