Please see my previous thread - I decided not to run this in 2015 but will do so in 2016 if I can get some interest, probably the last Sunday in April.
I am running a similar event in September in conjunction with the Society of Twentieth Century Wargamers.
I will post more details later but the attached link for the 20th Century event will give you a good idea of what it is about http://www.falkirkwargamesclub.org.uk/forum/viewtopic.php?f=27&t=158
