@halcro well, there is a sticker on your box with updated information that your OCC version has a boron cantilever. I think the box is the same with the only difference that i have all info about Beryllium cantilever right on the box, not on the sticker (there is no stickers on my boxes). Also the OCC box with computer code is definitely from the 90s, not from the 80s like the LC-OFC box without any computer codes.
Styli are interchangeable, but visually those cantilevers are the same, because they are both gold-plated.
Maybe AT covered any information about Beryllium after this metal was found toxic and prohibited? Maybe this is why there is a sticker. Also we don't know what is under the sticker, probably different information.
Anyway, this information is a proof. OCC comes with gold-plated Beryllium tapered cantilever, LC-OFC comes with Gold-Plated Boron Pipe cantilever.
There might be a version of the AT-ML180 OCC with Boron too.
At the moment i have only one AT-ML180, my version is LC-OFC with Boron cantilever.
