Well that was the point there was nothing wrong with the pipe, they have quite a thick shiny black paint on them, Just that it was seized and I couldn't finish the job in one go.
On old stuff like you say Mat you are faced with decay.
If the bled screw is fucked but not leaking, push the pistons in as far as they will go and clamp them, then loosen the feed pipe so it bleeds from there under pressure.
Alternatively if it leaks, Take the cylinder off and using the hole as a center drill it out with a 4mm
then a 6mm if the screw is an 8mil or an old 5/16ths. What's left can be easily cleared then and re tapped blown out and a new one fitted.
The only drawback to this advice is that few people have sets of taps and dies these days
