Chris and George venture into the Big Smoke to visit the hallowed and historic Long Room at James Purdey & Sons' Mayfair HQ, Audley House.

Dan Jago, Purdey's Chairman, lets them fiddle with perhaps the most priceless gun in the entire Purdey collection, and explains why it is that so many people the world over desire a gun made in the company's London factory more than any other, and why so many dogs are named Purdey.

Dan also sets a new bar for What's That You're Drinking, and helps the boys to debate the tricky topic of over-eager pickers-up, how to avoid being a 'greedy gun' and reminisces about a forgotten drive.
