Help finding replacement blade

In June 2023 I was out of town for my daughter's wedding. I went to shave with my Norelco with brand-new blades and discovered that the blades weren't spinning. I realized that although they fit, the mechanism for making them spin was different. I was frustrated, because the silkscreened model number on Norelcos always wore off, leading me to buy the wrong ones. I don't understand why they have so many different kinds of blades. I needed to shave, so I went to a nearby Target store, which was a small store. I made up my mind to not buy any more Norelcos. I bought a Braun, which is okay.

Now I want to get a new blade for it. The only model number on it is S5, and when I looked up replacement blades, the ones that came up were obviously not the right ones.

Do these companies do this on purpose to force people to buy new shavers? Can anyone help me select the correct blade? Unfortunately, the icon to add an image is grayed out.
