Hello Group,
I am here because I am writing a book and am hoping that the collective knowledge here can solve a few light mysteries. I am researching three different model Fresnels and need to identify each one. I believe the first one is a KLIEGL Model #53, in use from 1943 to '54. Am thinking that the second one is an Altman 65Q but thee seem to be so many out there between '54 and present day that it is still not clear. The one shown was in use from '54 to '73. The third, however was also being used from the mid '60's until '73 but have no idea what model it is... I would greatly appreciate any data on all three of these, if possible.
