There was a project to build a replica HP42 but it seems to have fizzled out.
Funnily enough I was going to suggest this in my first post as a more sensible use of 16 million pounds to promote an appreciation of U.K. aviation heritage. One idea in the 80's was to use it as a flying "orient express' . The late Ray Hilborne was sure it could be certificated based on the original HP work. Like the H.P. 0/400 project dreamed of in the late 60's early 70's - perhaps a good idea looking for a backer?
