If it is the master cylinder at fault, can I suggest that instead of changing the master cylinder, consider removing the piston (leaving the cylinder in situ) and replace the seal on the piston, which is probably worn and only a few pence to replace (just take the piston to a brake parts shop).
To get the piston out, remove the circlip from the cylinder body and the pushrod from the pedal. You might find that the over-centre spring becomes dislodged from the pedal. In that case, you might have to remove and re-fit the pedal. It's still easier than trying to remove the cylinder complete. I know, because the piston-seal-replacement fixed the clutch problem on my phase-1 Spider.
If there is no fluid flow, perhaps the bleed nipple is blocked, or the hose to the slave cylinder might be restricted in some way (breaking up internally?) Since new hoses probably aren't available, you might have to get one made up (again, at the brake parts shop).
