I'd say this is probably more likely to be an early styling proposal for what became the Alfa 1750 Saloon, although the shovel-front style is possibly a little too up-to-date for that (of course it became universal but early ones like the Lancia Beta looked quite odd when they first appeared, and I think the Alfa 1750 pre-dated that style. Maybe they tried it on this car and decided it wouldn't catch on...!)
