OK So the bodystyle seems to come from the 915.3xx chassis range of cars, but either Sport Coupe or Berlinetta is the closest I've been able to find. It could well be 915.365 as that's the only Coupe I can find (2 others with similar noses were made as cabriolets scratch that, they have headlight-to-headlight horizontal grilles, not self contained like this one), but I haven't found historical images, only contemporary so not sure what that means for name. The 'normal' body style continued on before and after these cars, though if my registry source is in dated order (no years alongside the chassis #s...) these do appear to be earlier on in the run of this overall bodystyle.
EDIT: I don't think it can be 915.365 as that car had different bumpers, grille, side skirt, lacks the indicators and wing mirrors and most tellingly is a split window example unless a thorough restoration was performed, which I doubt given the state of the interior in the contemprary pictures. Unless(2) they felt that the interior was worth protecting and only the exterior was restored, leaving me at a loss of other options.
I think this is a different car, perhaps slightly newer but the same bodystyle, but it seems odd that it's not (that I can find) present on seemingly complete(ish) registry websites.
