Are you sure the engraving on the bottom of the bowl isn't GA 395-131, which fits in with the Orrefors numbering system? I don't think they ever used the zero at the beginning. I was going to suggest that we would need to see photographs of the pieces before even giving a ballpark figure for a value. However, Cathy's list of links gives you a pretty good idea of the range of values. Value depends upon where you sell it, what collectors see it, and without being entirely facetious, phases of the moon.
