dirty water when bleading rads

No. The water is black because it contains inhibitor to stop the rusting. The fact that only a small amount of air came out also means that the CH system is in pretty good nick after so long.

Er, no, sir.
The water is black because it didn't contain ENOUGH inhibitor to stop the rusting!
Inhibitor imparts a yellowish hue. Rust is black.
I would not use Purimachos inhibitor as indicated above. It isn't recommended by any boiler manufacturer as suitable for corrosion protection.
unless you want to throw££££.get some quotes.AFAK.you don`t have to be CORGI to do a powerflush 
I thought Purimachos was an Indian Princess
