I have purchased a number of Brewster style viewers this year, one of the most recent was said to have be made by ICA in Dresden. I have found a few scraps of information about them from the eBay seller and others as well as information from Wikipedia. Does anyone know anything about these viewers and the company?
The Dresden-based German company Ica, was absorbed by Zeiss in 1926 and was already an amalgam of other Dresden based photographic companies .
If it is in fact an ICA viewer, it must be the youngest I have circa the first decade of the 20th century .
I came across a similar viewer that was possibly Lechner, but they were a company from Vienna.
