Is there a diagram? that's the easiest way to find out its heritage, I've not looked since I'm not remotely interested in an APS-C lens.
My first guess is Double Gauss, since most fast 50's are of this type. _________________ A Manual Focus Junky...

Should not Double Gauss have at least 6 elements? I myself thought it could be some Sonnar derivative. |

Indeed it looks like refined Sonnar design... I consider flat element in the middle to be aperture and not lens. |
