In the 90's scuzz my Workbench 3.0 was a hybrid too as I used to nick all the latest libs and devices etc. from AF and CU cover cd's. Ahhh... they were the days!
I wouldn't rely on any of your Amiga OS installs to be legit unless you have installed them yourself, fresh from the original unmodified OS disks. The reason I say 'unmodified' is that you have to be careful as some people did modify their Workbench disks, either deliberately or by accident.
