Not sure if this is the right place but the Staffordshire Regt Museum at Lichfield are holding a 20th Century Warfare Weekend on 16th and 17th April 2006. 1100 till 1600.
One of the attractions is a working 6 pdr anti-tank and apparently an re-enactment of the Baskeyfield VC action from September 1944.

I hope to be there with a stall. I've been to hte Museum befroe and they have Major Cain's smock and beret he wore at Arnhem together with a re-created WW1 trench.
