Saving Old Seagulls

I have a really nice condition 6 pint tank which I'd like to use on a restoration project, but I don't have the mounting adapter and the tank straps.
Does anyone have a set in decent condition that they could sell me?

Can you give us a clue as to which model of Seagull & which fuel tank your asking about?

Ahh - caught me out I assumed that the oval tank models were all for square heads but forgot to mention that it was to fit a silver century / century plus.
Did they ever fit the large tanks to 40 series? I only ever saw them fitted to the larger models.
