Film border with notch

[hiroh]

This is obviously medium format, but I didn't found any film that has borders like this? Can someone identify and explain notched borders vs normal ones that we can found in today's Tri-X 120 for example. Is this related to the camera perhaps? I think this was shot on Hasselblad.

A notch in sheet or strip of film would be directed inwards.

These are notches in the gate of the camera.

And yes those notches are from a hasselblad.

All Hasselblads have them. Enjoy the camera.
