1) The aircraft is still alive and well and currently owned by somebody in Linton, Derbyshire. If you want to search for the details on any aircraft it can be found at:
GINFO Database Search | Aircraft Register | Safety Regulation
Just type in the registration on the form and you will get chapter and verse.
2) As for monocular vision, you
can fly on an NPPL - initially only solo after qualification, but possibly take passengers subject to a flight asssessment. The medical requirements are less stringent than for the PPL and the paperwork is signed by your own GP. The only disadvantage is that you can only fly within the UK and you can't add extra ratings such as night and instrument ratings. See the following web site for details:
NPPL
Hope that helps
