More Pratt material uncovered

Every few months I am lucky enough to get sent another collection of old wargaming material.

Today I opened a huge box full of previously unknown Fletcher Pratt naval wargaming material. This belonged to Dan Dorcy, who revived the Pratt game in the 1960-70's and was in touch with Pratt umpire, Doc Clarke.

At last I have the formula and equations used by Pratt to generate his game. They were apparently the same ones as used by the USN for their wargames.

I am now hunting a shoe box in Yorkshire and another small box in the USA, then I will almost certainly have everything that has survived from those early Pratt games. Life is certainly interesting.
