hello everyone I recently acquired a "fallowfield london" petzval
I measured the focal length it's around 210/220mm and the front lens diameter is 66/67mm
This therefore makes an f/3.2
I read that Fallowfield made Dallmeyer clones, could this be one?
could it be a "Quick Acting Portrait Lens 2B" (2.75in diameter)?
thank you for your enlightenment and your knowledge
Sincerely
