Slosson Intelligence Test? Or some other measure?

If Slosson, that's got a mean of 100, a SD of 16, and a maximum score of 165. The result it gives is intended to be an IQish score (specifically for crystallized verbal intelligence).

The publisher reports good (0.83) correlation with WISC-III IQ scores, but this study (http://www.sciencedirect.com/science/article/pii/002244058790029X) reports low correlation with IQ for gifted kids, and a significant overestimation of IQ for gifted kids compared to the WISC-R and SB (probably the L-M revision, given the study date).
