The SV Confortevole were first presented in September 1957. Up to this date every SV was of Alleggerita type with sliding windows. From here on only the photos showing the side windows can keep SVAs apart from Convortevoles with descending windows. SVAs were built around 400 from April 1956 to April 1958, SVCs around 200 from September 1957 to April 1958 according to sources.
Zeltweg 1958: No. 69 is of course a SVA, the other car aside on the upper photo seems to be a SVC, the third is a SVA again, but I can not see the starting numbers to clear it with the entries. It will need to take a close look on some more period photographs.
In my post #59 in this thread I wrote the exact dates:
19580817 Flugplatzrennen Zeltweg GT (A): entry list
19570908 Coppa Intereuropa GT1.3 – Monza (I): entry list
19580907 Coppa Intereuropa GT1.1/GT1.3 – Monza (I), No. 33 which was modified by Bertone according to the Giulietta book by Anselmi, maybe like the SVZs because of a front damage.
