Cock on closing and thumb slot means that it's probably a 94 or 94 variant, but NOT a 98.
Also, the fact that it will chamber a 30-06 case gives me very little confidence. The shoulder and case mouth diameters are different enough that you might be able to get a 30-06 case into a 9.3x57 chamber. Definitely need to get a cast, or be prepared to own a 9.3x57 on a 94 action, which isn't a bad thing at all.
