Work recently took me to South Africa and now it will take me to London in early March. I will be taking my better half and will have a few extra days to wander. For gun-related wandering, I'd very much like to get by the H&H and Purdey shops just to say I've been. For a newbie, is an appointment necessary or do they take all comers? Are there any other recommended sites gun-related or otherwise? This is our first trip to the UK and I would kill to see my beloved Spurs play.
