All plastic kits, mostly Airfix with a few Revell chucked in.
The planes are 1/700. Lots of conversions of the capital stuff

British fleet

Jerry Fleet

HMS Hood, Ark Royal and Warspite

Jerry Big lads, plus converted Graf Zeppelin in the background

I really enjoyed the challenge of trying to make the various Airfix kits look like different ships.
My favourite is the Warspite which is 3 sections glued together.
