I saw the pages, and when it goes..."Designed by Franco Scaglione, and executed by Carrozeria Alemano" it's moreless what I wrote later, that is a Cisitalia 202 B with Scaglione bodywork...wikipedia says Scaglietti but I think it's Scaglione...and I found nowere that is not an Allemano design....I'm not sure because usually Allemano uses his logo on his design but I'm also aware that in the 2003 Monterey Sports Car Auction they gave the car the right name...I'm sure about Abarth engine also because I found a pic on an Abarth site that reports Cisitalia-Abarth 202 B from 1952.
In the end I wrote Cisitalia 202 b Abarth from 1952 and as you say it's not complete..it is a Cisitalia 202 B Abarth Allemano Berlinetta from 1951!
As soon as I'm back online I'll check better my answer...by now I know I'm a bit brief in my answers...
