Question about Braun Series 3

I don't know. But maybe the following will help: The packaging only says "Braun / Series 3 / Cassette / 32B". When I push up the long-hair trimmer on my 3030s shaver, you can also see the inscription "use part 32B" at the bottom (although it's hard to read). So the 32B seems to be important, maybe you will also find this 32B on your shaver.
