Hi
The buildings are a mixture of Empress' own range, Grand Manner, home built and a couple of heavily customised Miniature Building Authority contributions. The Empress buildings are really nice to work with and quite convertible. The Grand Manner buildings (eg the Convent) are quite an investment but make great centre pieces on the table (they are from the Napoleonic Spanish range).
The aircraft are a real hotch potch of 1:48th interwar aircraft from various obscure manufacturers as found in various dusty model shops up and down the country. It's a question of keeping your eyes open and getting lucky!
I was seduced into SCW at a weak moment but have never regretted it. It's a fascinating period to study and wargame and a refreshing change from killer cats on the Eastern Front! Yep, as commented on above, this game is clearly over armoured but it's bloody good fun! What's not to love about armoured trucks!
