The brand is the early 20th century German company International Camera AG (ICA), which had the 5-pointed star logo.

The 9x12 plate holders were made for their Minimum-Palmos 9x12 model, which was produced between 1909 (initially by Zeiss Palmos-Jena, then from 1911 by ICA) and 1926 when Zeiss-Ikon was created from ICA and a number of other manufacturers. Zeiss-Ikon continued to produce the camera and it's plate holders for a short time after the takeover too. I would say they are not exactly plentiful or easy to find - another reason for the vintage camera community to hate prop collectors I think

Here is a page from an old ICA catalogue - the slide in double-plate holder (Holzdoppelkassetten Einschieben) is in the upper right.

Thankyou for this info! Even with it though, I still can't find any. 'Not exactly plentiful' is right :lol
