Have you got your Ihagee folder from the Ebay seller yet? I've got an Ihagee Ultrix 6x9 folder dating from about 1930, and it's a beautifully made camera. It's got an Ibsor shutter speeded from 1 sec to 1/125 sec. Not very fast a top speed by later standards but a range of speeds that were I imagine very useful with the slow speed films fo the day.
The lens is f/4.5 labelled Ihagee Anastigmat but I don't think Ihagee ever made any lenses in house. The general opinion is that they bought the finished elements from Meyer and put them in their own mounts.
Ihagee folders took a back seat with the introduction of the Exakta range, and have been eclipsed by cameras from Zeiss Ikon and Voigtländer, which is no bad thing from our point of view as they usually go very reasonably.
If you get a chance post a picture of it - and some results when you've had a chance to run a film through it.
