Hi All, in case anyone's looking for a rad refurbishment, I've just had mine done by Viking Radiators.
I'm sure you'll all know that the Flaminia rad is more complicated than most.
Frank has done a very nice and thorough job, even refitting the original narrow overflow pipe into a new neck for me.
Here's his details in case anyone's interested:
