Funny you should ask that but heres a story .
In Oct 2002 my mate (who bought all my conversions) bought a blue mushroom tray full of Ford 5000,6600,tw20 and 5610 castings .
He bought them for me and I paid him the ?45.00 .In the tray were I think enough pairs of body castings for 45 tractors .
He iffed and offed at the time but took a gamble that I would buy them when he returned home .It turned out that he had bought them off Brian Norman and then thr ironic thing was I buy all of my bits off Brian so he has made a lot of money out of has old castings .I have in the region of 20-25 set left so they are the main part really .I just struggle to get wheels .
