A couple of weekends ago I went down to the South East London Wargames Group's show called SELWG. It's a one day trade and show event held down in Crystal Palace.
It's a great vendor show, lots of vendors who don't go to many of the smaller comps. They also have lots of great demo games in a variety of periods.
One that caught my eye was an Israeli vs Lebanon gaming being played in 10mm using Cold War Commander.
Another game I saw was a Vietnam gaming in I think 15mm. They had a 15mm Chinook on the table
This was a 15mm WWII game set in a Polish city
