Firstly unit 501 CV-35 [37] apparently was never manufactured...

Till now I haven't any clue for this model. But those CV tankette had a lot of "on field" modifications.

...Looking at the other tankettes I can find no evidence that these other configurations existed either...

unit 2 CV-33

existed but with:
a single Fiat 6.5mm mod.14, the so called "I Version" soon refitted with a twin 8mm MG.
see my previous post of this thread.

unit 368 CV-29 Ricerca and unit 369 CV-33 Ricerca. The 6.5 mm MGs were all fitted singly these have pairs of 6.5 MGS.

AFAIK, all CV-29 had only a sigle 6.5mm MG.
I'm not aware of any "Ricerca" denomination for those vehicles.
In winSPWW2 it's slight different from the "father" version, but I don't know what "real" CV version they want to represent.

unit 503 CV-38 [20]. Can't find anything for a 20mm AT gun plus a MG.

AFAIK, the only AT weapon for this tankette was the Solothurn, in the two configurations I wrote in the corrige.(see also a picture posted by Sicut Leones here:
http://www.netwargamingitalia.net/fo...?t=9447&page=2)

unit 504 CV-38 CC. only a single 20mm AT was fitted not 2.

Again, I'm not aware of the existence of such CV configuration.

unit 505 CV-38/Brixia. possibly a brixia motar could be carried but it would probably have to be dismounted to be used.

Existed, it's an "on field modification" and the Brixia mortar is mounted(fixed) externally (there is a picture in the Pignato book)

unit 506 CV-38 [13.2]. only one 13.2 MG was carried not 2.

Existed, and only one MG is correct (again see Pignato).

Also for unit 500 CV-35 [20] I dont know if ayone can confirm this one way or the other but Im guessing it probably had a sight and so may deserve better than 10 for range."

See my answer for the unit 503 for the armament.
Anyway if the 20mm L65 BGun (weapon 229) is the 20mm Breda 35 L65 the effective range should be more: Tarrif.net claim 2000m for AP (well, 1mm penetration...) and Pignato speaks of 5500m...

Thanks in advance Chuck.

You are welcome.
