Les,
If my memory serves me well, it comes from a 4A Folder. Speeds run from
T, B, 1/25 to 1/100 while the F-stops run from US 4 to 8, 16, 32, 64.
What is the difference between F-stops and US stops? Never realized
that there were different kinds of aperture.
Actually, I just discovered faint engravings on the side of the lens
reading Rapid Rectilinear Bausch&Lomb Optical Co.. So this would be
different from Scot's anastigmat lens. What would the difference be
between the two?
Thanks for your help.
