JulieThere's undoubtedly a N173 with the same picture.
Lew Lipset doesn't say word one about "albumen" or "silver nitrate," and David Rudd, though he may think he makes everything clear as glass (HA!), doesn't. My INMPRESSION from reading Rudd is that albumen prints--all Old judges, n173's and N167s, are albumen prints and WERE NOT MADE FROM METAL NEGATIVES.
Anyone with better information, please contribute.
It really makes me mad that Lipset and Rudd, experts in 19th century photography (esp. Rudd), don't mske this clear.
Rudd does say that tintypes, and a few others earlier than Old Judge) ARE made on metal--in fact, ARE metal.
