[NJARC] Marconi catalog online

[Alex Magoun]

For some professional images of unique and common radio artifacts from
Marconi's turn-of-the century apparatus to RCA/Cunningham vacuum tubes, you
could do worse than to visit the 655 catalogued items at Oxford University
from the Marconi company's archive:
http://www.mhs.ox.ac.uk/marconi/collection/catalogue.phps.  It's obvious to
me that some of you could identify or date items more specifically than
the catalogers, but I'm not sure that they can be contacted.
