My measurements say your friend is correct, that the thread is a 7/8 fine Whitworth. Unfortunately, I haven't found a modern source for the studs or nuts. The nuts are sometimes available from people who are scrapping a rim that would be unsafe for use. If I were scrapping a rim, I would also recover the studs since I don't know another source for them (but it would be an effort to remove and clean up the studs). Even cleaning the threads isn't as easy as you might think because the taps and dies seem to have pretty much disappeared too.
Have you tried contacting LWD Parts?
