Just checked a photo I have and it doesn't have the step, so it looks as though its the 1943 version.
I've got a few things running through my mind now, green paint (with yellow under it) all over the crankcases and a 1943 mag dyno. Although the engine number matches the original number for the bike which is 1947.
