Shimano MTB 9 speed cassette

[Fatmat]

Hello, I’ve not seen a Shimano cassette that breaks down fully, not like most SRAM ones do. Unfortunately the code isn’t on the lock ring. Does anyone know what model it might be? It came off an LX hub / Mavic 517 SUP. Thanks

Is it not just missing the 3/4 bolts or pins that hold it together, all except for the last 8th and 9th sprocket?

That’s right, the largest 7 bolt together, the 2 smallest just sit on top. I’ve never seen a Shimano like this, it’s not to say it’s rare, but I have seen a fair few over the years, just not like this one!

Sorry, think I misread your first post....

Most are riveted, but I have seen them bolted too, can't help with part numbers. But from the lock-ring I'd say it's a higher end one.
