here is a picture of mine.
The light can be put to the front or back, I've got a decalled version with the same light put on to the back.
I checked with several other White rotaries I have, and they all look the same. I even checked and the front plates were all the same.
So I went out to the shed where I have two parts ones - and found a slide and even still had a bobbin case in one . . .
I've got almost as much extra White stuff as I do all the others combined.
