I don't know what happened to the Sherman but things were a little confusing down there because some vehicles belonged to dave Arnold, some to the iow museum, some to bovvy and a few to other private individuals so the whole thing became a bit of a giant cluster f@ck .
I've heard various contradictory stories of ownership, which to be honest make me laugh at the duplicity involved in this hobby. someone should write a book about it one day anyway if I had to guess I would say the Sherman belonged to the museum but that's as much as I can say until I go down there which I need to do soon.
