Stefan,
You need to post this inquiry on the Iris Forum. There are several knowledgeable folks over there regarding historic iris which I believe both these are likely to be. They are appealing, but it's usually very difficult to identify an iris with certainty from only a photo. Always worth a try and you may come up with specific names which may enable you to identify them later. At least they are likely to predate the time when it became difficult to transport plant material across international borders.
