What are these "slots" on the eccentric BB?

What are these "slots". It looks like the cylinder the BB was made of wasn't big enough and it was cut to fit around the eccentric :) I couldn't find any picture resembling this on the net.

Matt2matt2002:
Are they the slots that the EBB spanner fits into? Then you can turn it.

flocsy:
I don't know, but this picture IMHO is supposed to be the FRAME, the EBB is inside the frame. Here's the whole picture: It's a Raven or maybe Raven Tour

PH:
Does look a bit odd.  What's the context?  Bike for sale? What bike? What does the seller say?

flocsy:
Odd, isn't it? It's from here: http://thorncyclesforum.co.uk/index.php?topic=14900.0
When I asked the owner in email he replied: "casting" which makes no sense to me, neither does it look like that, nor does any of the other thorns (or any other bike with EBB) that I found on the internet have anything that resembles these 2 slots.
