I have two books on GC12, the Storks. One is by Norman Franks and Frank Bailey, the other is the Osprey elite Unit series by Jon Guttman. Both mention a period where SPA 3 used "Green" numbers instead of the normal red. In the Franks and Bailey book Guynemers SPAD XIII S 504 is drawn as having green numbers. In the second book by Guttman it is the normal red. Hobbycraft obviously based their 1/32nd kit markings on the former and supplied green numbers. So does anyone have any thoughts or definitive answers?
