  There is an old gentleman in Salt Lake City who specializes in vacuum
tubes.  He has a book on Western Electric tubes, but thinks the book
predates the D-86327 tube.  He thinks this tube is a big red klystron tube.
He carries the 101-F and 102-D.  If you're interested in buying or selling:

    Salt Lake Instrument
    129 W. 1700 So.
    SLC, UT 84115     1-801-487-2541

His inventory may be in the 100's of thousands!  He buys out other vacuum
tube dealers when it's no longer profitable for them to carry vacuum tubes,
but he'll probably try to charge you full price.  (He finally came down
from $100 to $40 for an old GM tube I bought from him when I told him I
could get a new tube, different type but similar functionality, for about
$39!)
