It would appear that Joe Baugher's site for Military Aircraft can only be used to identify planes (maybe). The 1946 - 1948 aircraft before 1000 series read as 46-XXX or 47-XXX, or 48-XXX. However people seem to think that an extra zero has to be added for some reason and that the proper numbers had to be removed. I had added the proper Joe Baugher aircraft numbers and they have been removed and the aircraft pictures have been moved back to the unrecorded numbers.
