Catherine Southon

The third leg of the antiques odyssey with Catherine Southon and Philip Serrell sees them taking the old Citroën through the West Country. Catherine decides to change her buying strategy, going for more of Philip's rust-and-woodworm fare. True to form, Phil diverts to the beach and asks a local fisherman if he has some antique chandlery to sell.

Catherine Southon and Philip Serrell are travelling along the beautiful Cornish coastline in a classic Citroën DS20. Before the auction in Bristol, Catherine heads to Porthcurno to see first-hand the incredible cables that stretch from this little village, along the sea bed, to South America, Australia and India. Meanwhile, Phil goes for a ride on a replica of the Puffing Devil, one of the first steam-powered vehicles in the world.

Philip Serrell and Catherine Southon set off from the Midlands in a 1970 Citroën DS20, hunting for antiques in Birmingham and Stratford-upon-Avon before heading to an auction in Salisbury. Phil spends a lot of his cash on a 19th-century butter churn, whereas Catherine finds two attractive 1940s compacts.

Catherine Southon and Philip Serrell battle it out for the last time. Travelling through South Wales, the old Citroën DS20 takes them to the final auction in Wells, Somerset. Catherine heads to the Royal Mint and finds out how Sir Isaac Newton revolutionised coins to prevent forgers making a fortune. Phil breaks from shopping for a little lesson in culture at the Bristol Old Vic and discovers why it is a miracle the building still stands today.

Catherine Southon and Philip Serrell continue their antique adventure in a classic Citroën. In Winchester Catherine finds a jolly nice croquet set, and in Alton a rare 1930s novelty biscuit tin, both of which give her a chance of huge profits at auction in Christchurch. Meanwhile, Phil learns how flying boats gave us the word "airport".
