I would draw the hole on the ?ZY? plane instead of the face of the material. Then extrude cut "through all".
Caveat...
I don't use sheet metal so if this doesn't work in sm then I would reconstruct as a "part", not sheet metal. Then it should work.

No problem using extrude cut insted of sheet metal cut.
But how to manufactoring this part, those skew holes is not a sheet metal operation.!!

Use the "Hole Tool " in sheet metal, instead of the "Sheet Metal Cut"

Slipstick -- Is that a (round) hole that is Punched after the strip is Formed or could it be an Obround punched before it is Formed? That would be the question I would ask.
As somebody who served his apprenticeship under a German Machinist's Guild (my "translation") Master Tool & Die Machinist, I suspect that it was compoundly punched in a Closed Form die-set. My "suggested approach" would be that the piece was "grabbed and formed" into the (from the "open" side of the "V") and, when that "closure" was made a second "stroke" punched the holes through the angled faces. Such die-sets were not "common" in the late-1960's, but I saw and made such things. [It is hard enough today to find a machinist who knows what a tooling ball is!]Without having an actual example of the original part, or some other inside knowledge, I doubt I could ever find out. It was a part of an FW 190 fighter. I don't know how the Germans routinely did things then.
Unfortunately such people are all too common these days!I couldn't imagine a machinist not knowing what a tooling ball is. Best referencing/setup method there is imo.
