David and Jay are at the Kelsall Steam Festival in Cheshire, where they are on a quest to meet talented tinkerers.
First they meet with Steve, who has brought along a 1948 bus that he has lovingly restored. Hoping to learn how to make a traditional sign, he is partnered up with expert signwriter Kerri Williams, who is excited to help add stunning artwork to the back of his bus.
Meanwhile, David and Jay head off to meet another Steve who has been restoring old BBC outside broadcast trucks. They take a tour of the truck and learn about the importance of saving these vehicles.
Finally, the pair meet neon sign makers Tony and Sam at their workshop. They learn about what is involved with neon sign writing and are both invited to have a go.
