HMS Incomparable Battlecruiser

From Wikipedia: "HMS Incomparable was the name given by Admiral John "Jackie" Fisher to a proposal for a very large battlecruiser which was suggested in 1915. The design was intended to mount 20-inch guns, which would have been the largest ever mounted on a warship. Despite research into the concept, it never entered the design stage or came close to being built." 

Note: there was no definitive HMS Incomparable design, and this model incorporated features from several commonly published illustrations & models. 

This model is scaled to fit in with most Historical Board Gaming products (but it is not an HBG product of course). So, the scale is approximately 1:4300
