Unfortunately, no HA 1112 in Spanish service was ever green or in some sort of camo. This has long been debunked. A lot of the reason for this myth is that there are some color photos which show apparently green Buchones, which is due to two factors: 1) Bad/overexposed color film quality, as most in Spain was very, very basic at that time, and 2) The Buchón´s weathering. Buchón aircraft were painted with two schemes in service-the metallic and blue one, and the all-blue "Peugeot" one. Excessive weathering, maintenance, etc provoked the color of the all-blue ones to sometimes turn a grayish blue. Sometimes, crews would improvise on this and would touch up the paint in badly affected areas. The contrast of fresh, new paint and old, weathered paint made a camo impression.
Observe here. This is actually the "MAPI" aircraft. The pilot named this aircraft MAPI as a shorthand of María del Pilar, which was presumably his girl friend.

http://www.aviationcorner.net/show_photo_en.asp?id=167833C.4K-162, as seen in the photo, was in an air museum in Andalucía (I think) in the 70s before being bought by a foreigner some time in the early 80s. Its paint scheme was very obviously applied after it was removed from service. It could have been done to match it with the C-2111 in the background after its original paint wore off, which wore that same splinter scheme in the late 60s up until 1971-3 when they were retired.
So, the whole camouflaged Buchón myth has been promulgated by someone that saw the above photo of 71-5 at Gando and saw it as a camouflage scheme. This never was so.
Any skin based on it would definitely be nice and cool though, it is just that the camouflaged Buchón myth has been circulated so many times that many people seem to think that such a thing was true since so many modelers and artists have portrayed the HA 1112 71-5 and others with camo...
Here is a forum post with the exact banner picture and the exact same argument as here;
