Hum......my old 54-3100 bought new in Memphis does not have them. I would be inclined to think that a larger dealer had them made up. Therefor try to keep them pristine or contact one of many decal providores and you may get them duplicated. It has been years ago but i got a fellow in Denver to reproduce H2O slip decals for a 55 Buick. Keep trying. Doc


Currently making 1954 3100 better than new and Genetics
