Yes it was the 1/28 scale kits together in one box. The Triplane was molded in red, the Camel in green, and the SPAD in tan iirc. The SPAD was a huge problem for 8 year old me because I did not have any brown paint for the camo, only green and red which I mixed together on the advice of my parents and which predictably looked awful. I built them all, can't remember their eventual fate but I'm guessing it involved copious amounts of lighter fluid and firecrackers.
wasnt alive yet for that one but had later boxings of the DrI and SPAD in the 70s - these were really great kits from what I recall - lots of details. I seem to recall figures for ground crew in at least one of the kits?
