You may have a challenge finding the correct decal. Here is what I can tell you:
1) According to Guy Fay's "Letter Series Tractors" book, the "McCormick-Deering International Farmall" decal was only used on tractors exported to Denmark. Evidently all other export tractors were changed to "McCormick International Farmall" in 1949. I don't know if all Cubs destined for Scandinavia went through Denmark or if your tractor migrated from Denmark as a used tractor. I suppose either could have happened. There is also some chance the hood was replaced with a '47 - '49 hood from another tractor.
2) Accurate reproduction decals of the common versions are hard to find. You are looking for an unusual version. I doubt anybody has made this one. You may have to have them custom made. I strongly suggest you take good pictures before removing the old ones. Include a measuring ruler in the pictures. According to Guy's book, this one is number 1001108R2.
3) The only leads I can give:
Mike Schmudlach posts here once in a while. He has some experience with European tractors and may be able provide a lead.
Ken Updike at http://www.cngco.com/
has made some decals from the original prints. If he has the correct print, he may be able to make what you need.
Jean Cointe (COINTE.S.A@wanadoo.fr
) is a collector in France, whose family has a long history in farm equipment and IH. He may be able to help.
Good luck with your search and the restoration project.
