From my half ass google searching skills, this seems to be a 1939 Packard Super 8 hood ornament. Is this correct? Not sure what sub-model it would have came on... If you have any more info on these, please feel free to share! Thanks,
It is the Goddess of Speed and was used in various forms for 20 years or so on the more expensive Packards. I do not think they were used on the junior series cars (but maybe, they could have been specially ordered-who knows). Yours looks similar to those used on the late 30s customs and early 40s Clipper models but it appears to be missing the glass wing. Look on the underside of the top protrusion and see if there is a groove where a piece of glass may go. I believe you are correct a late 30s Super 8 would be a senior series car and may have this mascot or one very similar.
