I'll check through my old kit as I must have one or two lying around. If you can't get it out using spikeychris suggestion then email me with your address and I'll send you one (free of course). It will probably be Tuesday before I can send it though.
If you remove the drive there is usually a cover that comes off quite easily, sometimes with a couple of screws, sometimes without screws. If you remove this you can remove the foreign object. But before you remove the cover, just hold open the floppy door and give it a shake as it might just fall out. This is a common thing to happen in my work.
