This pattern is, again, from the 1930 issue of Beyers Modenblatt. They look to be like tap pants–sort of like long underwear. But, like, short. The size on the pattern sheet is listed as 112 cm (hip measurement).
They're made from 85 cm of 140 cm wide wool knit fabric. Again, because the original instructions are in Fraktur I can barely read them, but the illustration suggests these use some sort of elastic for the waist and legs. Even if the instructions DON'T call for elastic, go for it! It's a free pattern with virtually NO instructions! Do whatever you want!
You could also technically knit these if you figure out your gauge. They would look quite pretty with a simple lace pattern on the legs.
This pattern is the front and the back, so you'd cut two and then seam 'em up. There's also a gusset.
No seam allowances, hems, etc., as always.
