Ermanox-Reflex Plate cameras 1927-1929
From the Ernemann company Zeiss Ikon inherited the Ermanox-Reflex camera for the 4,5x6cm plate format.

Even during its short production/selling time as a Zeiss Ikon camera the Ermanox-Reflex changed from Bestellnummer.
The next table lists the original Bestellnummer starting in 1926 next to the newer one, late 1928/early 1929.
