Now this is something completely different. After
extensive research I have established that this is pre 1922 Postcard Plate
camera but precisely what year I don't know. I have found reference to it
in a 1922 Ica products catalogue and it was already an established model
at this time. What I'm looking for is a date when the "f stop"
EV range was standardised because this has unusual f stops of f8, 12.5,
18, 25, 36 thereby using the second third instead of the usual first
third. It can use either Postcard sized plates 90 x 120 or a roll film the
type of which I have not yet established. This particular example has, by
the ingenuity of a previous owner, the capability of using 120 roll film
with special spindles and a home made screen for 60 x 90. It's in
absolutely immaculate condition and fully working. Whether or not I will
be able to use it is another matter. I could use the 120 film option but
this would not do justice to it, I would much rather try to obtain some
plates/holders and use it with sheet negatives. Watch this space.
The wait is over, having tried, unsuccessfully, to
create plate images I have gone for the soft option and used it with a 120
roll. Incidentally the adaptors were for 620 not 120 as I originally
thought so I had to re-roll the film onto the 620 spindles.
