Sheldon and Park Tools just confuse me, and I'm not even sure whether the
BB is a cartridge one or not. Any help gratefully received.

T'aint a cartridge.

The RH side (chainwheel) will be a LH thread, and vice-versa.

At a guess, unscrew the lock ring - either the tool with a hook on it, or
hammer/punch. Then unscrew the cup using the flats you can see. (I'd use a
vice for that if I didn't have an appropriate spanner).

cheers,
clive

I agree with Clive. strip the frame, undo the lockring, hold the flats
in a vice and turn the frame, easy-peasy.

....just bearing in mind that the two cups unscrew in opposite directions.

Alternatively take one large 2 or 3 inch bolt, place washer on one end
pass through the bottom bracket RH side cup so now it is firm up
against the cup on the inside, place another washer on the bolt on the
outside of the cup and then add the nut then tighten the bolt -
because the RH cup is reverse threaded this should then unscrew the
fixed cup. Plenty of plus gas and lots of wellie also help.
