Yes, I see what you mean. Your's has a different face. Maybe it is not a "ram". Aren't rams the males? Your piece looks more feminine, with a prettier face. Aren't they called ewes?
My best suggestion, a good antique store/mall has books on Lalique. Some libraries also. I would ask the mall manager to help you find the item in the book, and if it is in there, then go ahead and buy the book.
I hope it is a Lalique. Keep us informed. KB
