Neither AJS nor Matchless, what you appear to have there is the remains of an electric start Norton 400cc Electra.

The engine side casting is most certainly off an Electra, and the forks are Norton 'Roadholders'. I can also identify the points cover by the casting number "20864" as being from a Norton lightweight twin 250 Jubilee/350 Navigator/400 Electra model.
