Realistically, they're more likely to have come from a plastic kit in the 1960s, perhaps originally squadron roundels from a WW2 fighter or bomber. Quite apart from anything else, I would expect 1930s-applied decals to be dry and brittle by now (but i suppose quality and the conditions they've been exposed would also play a role here).
Having had a good search online (I hope MI5 weren't monitoring me!), I am tending towards it being a logo with Italian connections, but I cannot find a match.
