I have two lenses that I wished I knew more of their provenance: a 14 1/2" Verito, which I bought from an individual dealer. He said that the lens was used to photograph the Beatles, when they first came to America in 1964. Alas, I never asked who the photographer was. I'm curious about the name on a second lens - an Aldis Anastigmat that I bought from a dealer in India. Stamped/engraved on the side is the name "Babajee Sakharam & Co Bombay". Was this an individual photographer, who had ordered this British lens from England, or, I suppose more likely, an Indian dealer in British lenses? A simple Google search doesn't turn up anything.
Knowing some small tidbit of a lens's history make them special.
