Here's the mascot you seek:
http://www.ebay.com/itm/Rare-Vintage-An ... 1c28c62447The critical thing to look for is that the tips of the ram's horns are complete as this one appears to be. The finish isn't great and it would need to be rechromed...adding to the cost. I'd say this one is already overpriced by at least $150. Bargains come along once in a great while, so patience and constant vigil is in order. (I snagged a nice one for $150 about two years ago). If you're looking to have the car as a driver, an option would be to buy one in decent surface condition but with slightly broken horn tips. That's what I've done since it's quite likely that stones kicked up while driving will eventually hit those horns. I keep my best one for shows only.
Where are you located?
