Is this clutch basket a basket case

[nick crisp]

Hmmm. That's got me stumped. On the first photo it just looked like a machined surface from the factory, but second pic... that's a puzzle. Now looks way too deep and uneven to be that. Strange also how where the "fingers" (yeah I know, crap terminology!) that the clutch plate tabs slide up between don't seem to be marked similarly where they join with the main casing.  :\
