I believe there's one in my local air museum, along with a B52. Sneaking them past the security guards might be a bit tricky though - they don't exactly fit in back pockets :-) I have a few leads to chase up on the WWII fire control computer now, from various sources, so a bit of progress is being made. Thanks to those on the list who replied! cheers Jules __________________________________________________ Do You Yahoo!? Everything you'll ever need on one web page http://uk.my.yahoo.com
