Here is what I have found out so far from various sources. From what I can see Wikipedia seems as reliable as some of my Aircraft books and various websites. I don't want to get bogged down on this issue, I will just be using it as a rough guide, but I would like to make it at least a little bit plausible. The planes in bold are the ones I'm struggling with so far. Any help would be appreciated!
Nieuport 52
Total of 56 with 8 of these falling to the Nationalists. The majority remained in government hands, with only eight falling into nationalist hands, being supplemented by three Republican aircraft that mistakenly landed in Nationalist territory on 21 July. The Republican forces were strengthened by Hispano-Suiza building a further 10 aircraft from spares in August–September 1936. The mainstay of the pre-war Spanish fighter force. The serving aircraft at the outbreak of hostilities were more-or-less evenly divided between the two sides. (Website)
