The sphinx decal seemed to be rather delicate, it's one of the harder to find in good shape.
I must have been lucky with my machines, but they were later 1934 and 1950 models. I have cleaned and polished carefully but I suspect there is a layer of shellac over the entire gilding. Wonder why the Sphinx decals have been less protected, they are certainly all over the machine compared to the simpler ones?
