Interesting thingies. I can't help on the purpose.
Some more detailed pictures of the tools might help us assign a date to the bulk of the tooling, although this looks like it could be a mixture of periods. Some wooden planes were produced well into the 20th century. In fact, EC Emmerich, in Germany, is still producing them.
Interesting looking tools (the background tools, not just your what's-it tools). What looks like a marking gauge, visible in most of the pics, with a beam in what might be ebony - dark and red-brown wood - looks like a stunning piece.
