The animal figures and other details are very similar to a highly finished Johann Springer (Vienna) Mauser 98 that passed through my hands a few years ago. That rifle was dated 1948 and inscribed with the name of a U.S. Army officer. Without any maker name or proof marks it would be hard to tell whether the Remington was finished by a German or Austrian shop, but it was certainly commissioned by a U.S. serviceman immediately after WW2.
