It isn't in the TRO 3025 (3rd printing 1987). It is the House Liao sourcebook (pubished 1988), along with the Cataphract-1X. All the standard-tech versions are in TRO 3039 (published 2008), & the high-tech -3L appears in TRO 3050 (1990).
"During the Fourth Succession War, House Davion forces captured many Ravens as they slashed through the Capellan Confederation" (TRO 3039, p.224). I think the key word here is MANY. That's why the concept art is painted in AFFS colours.
Besides the House Book is was also featured in the TRO 3031 (1995), which was only released in Germany as far as I know.
