That is very interesting Richard, I found the patent
looking for the number, that is the 150 mag.
All the best
Carlos
If you posted the number I somehow missed it. Google
Patents allows text searches on any patent in the U.S.Patent
office without regard to date. The patent office site allows
text searches only on patents issued from 1976, one can
search only by number before that. The Google site also
allows downloading patents in PDF form, a great convenience.
It is a great service. I don't think it has patents outside
of the U.S. but I could be mistaken. It certainly would be
great if it did. Most of the historical patents in the field
of photographic optics issued in other countries were also
patented in the U.S. but not all. Actually, sometimes the
U.S. version has more information than the foreign patent,
for instance the patent for the Tessar is much more
complete.
