Based on your questioning, I made another research and that's what I've found out:
A. Chinese mascot for this Neoclassic car
B. After market hood ornament that fitted on Rugby Motor car
C. Original Praga Car hood ornament
D. After market not related but fitted on 1951 Jaguar Mark V
E. Original hood ornament, (3d version of the logo)
F. After market hood ornament that fitted on Baby Cid motor car
G. After Market hood ornament that fitted on Cottin et Desgouttes
H. Original hood ornament of the Delfin by Julio Fuste
I. After Market hood ornament that fitted on Gardner Serpollet
So I'll keep open for the original market mascot and reveal the others.
