Thanks , when i restore i like them to look like a museum piece so it was intentional. The color is an engine enamel in spray can form . In Australia its called ford blue . Pre 1980's ford Australia pained their motors blue . I sometimes also refer to it as royal blue but that is incorrect . I like the engine enamels because they look good but they are also very tough and impervious to oils . I have quite a few restored machines from skivers to sewing machines . In another post i have some photos of restored singer 31K48 machines . search 31K48 and you will find them . My real love is restoring singer 29K patchers . If i find a thread on here i will post some photos or i might even start a new thread .
Cheers TomE
