i.e. the open part of the angle face your legs?
In the hand book the drawings look to be this way,
with the screw heads that hold the shelf also being shown outwards?
Also is it just the bare painted metal finish, & what colour? Or is it padded as in the later 1000's?

And what colour is the original cardboard shelf and what finish is it?
And how is it held up at the back please?
With thanks,
