Railton Cobham perhaps? Exact year is a little tough, coachbuilder (and the coachwork is, ah, rather unfortunate) a bit more so. I'll keep looking, but in the meantime I'll hazard a guess . . . many (most?) Railtons were eventually bodied by Coachcraft, but that doesn't seem right for this big saloon so I'll say it's a 1934, body by Ranalah?
