Gary,

There are no other Stealths in the USA. There is a huge collection of them at Datchet, a reservoir just outside of London, and scattered throughout the UK. I believe there are just a few on the European continent. I visited Datchet (http://www.dwsc.co.uk/) last time I was in London and found it to be quite a friendly bunch. The neat thing was being able to see all the different iterations of the Stealth over the last several years. I should really dig out the photos for you. John Pierce is quite innovative and his designs seem to be ahead of there time in many respects.
