I probably can't help but anyway I'd like to say that you have to be more clearly if anyone should help you.
By "Escom WB 3.1" you probably mean the disk set for the A4000T with a disk-based workbench.library, don't you ? Other than that all disk sets are the same AFAIK.
And which one do you mean by "the first of 6" ? There is Workbench, Extras, Storage, Locale, Fonts and Install, but they don't have numbers on them.
Bye,
Thomas
