Support load-bearing or not??

[sebbep]

we have bought a house from 1939 we want to open up between the kitchen and living room but now the question is whether it helps to support the upper floor or not here are the old plans from -39, the red-marked wall we want to remove, we have opened up a little of the wall to check underneath there was an empty space of maybe 10-15 cm with sawdust as insulation underneath, the wall has masonite and 50mm rough-cut lumber similar timber.

I would guess that it is not load-bearing - the center wall should be load-bearing. But always best to wait for Justus's advice.

The house has a plank frame. The wall you want to remove consists of 2-inch tongue and groove planks. The problem with houses built in this manner from the 1920-40s is that you can never be really sure about the direction of the floor joists. The houses can be very unsystematically built. In this case, however, I dare to say that the red wall is not load-bearing. I base this on the proportions of the kitchen and living room, as well as on the shape and placement of the chimney.

Thank you so much for the answers!

Now we have another question regarding a different wall, only the blue-marked area we would like to open up to create a more spacious hallway, there's a picture of the basement which indicates that it's not load-bearing, but to be sure I am asking.

Blue wall is certainly not load-bearing.
