As above, it should *just* screw out, anticlockwise and BITD that design was 26 TPI Raleigh.....
Are you desperate to remove it?

Re: What type BB do I need for this?
Ah, now - there's a thought. Never even thought it might be removable, will try it tomorrow.
Is it supposed to go back on over the bb though, if not, what's it for?
Is that a stupid question?

Looks like a Raleigh type. The cup on my MK3 Moulton looked exactly like that one. If it is a Raleigh, the threads will be different.
I got a set of stilsons on mine and out it came with not a lot of fuss!

Re:
Yes it looks like a Raleigh type to me, but before you get too heavy handed with it, check which direction to turn it.
My four British bikes (1953-198
are all CLOCKWISE to UNSCREW the DRIVE side bb cup.
Why do you need to remove it? Have you not got the rest of the BB? If it's 26tpi you might struggle to find a replacement.
A removal method that hasn't failed me yet, is to use an M16 bolt, nut and a star washer. I put the bolt through from the inside, and use a socket to hold it. Then tighten the nut and washer down from the outside using a spanner, then keep turning the spanner (clockwise) to extract the assembly complete. If it won't budge, give the spanner a whack with a hammer to crack it off. If the bolt slips in the cup, try a star washer under the bolt head as well as under the nut. If none of this shifts it, you will probably need to use heat, or weld the bolt to the cup, but then it is wrecked.

Re: What type BB do I need for this?
No I haven't got rest of BB. So, I'm going to have to try and remove it, hopefully it isn't too much of an issue, but will heed advice above.
HOWEVER, can anybody tell me what type of BB replacement I should be looking for to fit the remaining shell??
