Agusta certainly used to have that sort of printed material as I have a number of copies relating to the A109 produced by the Sales and engineering division. Hard copy, in colour but not glossy. Unfortunately those I have are dated 1996 and 1998 so some things will have changed.
The references on these documents are A109 Power PC-TD58 dated March 1998 'Customer's Technical Information' that boils down to about 40 pages A4 and the Appendix A Performance Diagrams PC-TD58A seven pages of graphs.
Sloane did an extract + comparisons with the competitors that I also have but again that was 1990s.
