Favilla C-5 - crest logo on a tilt?

[pickitPaul]

Does anyone know about these? I have a mid to late 50's. All Mahogany. ladder braced

I know its not a 1960's model, because it was my fathers, and I learned on it 38 yrs ago when trying to begin playing guitar. Hell of a neck to start on - very wide classical 2" but I fought on.

I read some place that if the family crest logo is on a slight tilt, that can help date it??
