Two tier Accurate casting co. lamp

Alot unknown about these lamps. We don't know whether or not they are a set, or even from the same company. There are no markings on the smaller lamp that indicate a company or artist. The larger of the two says accurate casting co. inc. on the bottom, but there are no other identifying marks that I have been able to find that indicate an artist at all. I am doing this appraisal in secret, so I don't know much except that her grandmother gave it to her.

Good
