I have had a close look at Rob's images.  At maximum, WX is a close match to HD 163798, (2000) 
17:58:46.84 -17:45:30.0,  V=9.44  B-V =1.19.
At  (presumed) minimum  WX Sgr is a good match to TYC 6254-2472,  V =11.52 (0.027) from ASAS-3.
These values, 9.4v and 11.5v  are consistent with the GCVS range of 9.3 -11.3p. Perhaps the true 
minimum is slightly fainter than the value derived from ASAS-3 data, being very sharp.
