I think I've seen the Gaz radiator shell before as "somewhat shallow" in the "widow's peak" pattern of the upper shell. Not quite like American production. Below GAZ 1930ish

You can see the GAZ-A radiator shell in this photo of the GAZ-A that is located in the basement of the Polytechnical Museum in Moscow, Russia:
