You're right not to change things in Simbad: the M1-star is the more likely
choice. The errors of VB(lanco) positions are far larger than P=1 (+-0.1 arcsec !)
as quoted in CGCS and they increase with increasing faintness. They seem
however not to exceed 1 arcmin at V = 16 (as seen from identifications in 2MASS)
usually, while +-0.2 arcsec is reached for V= 10. Andrejs Alksnis (CGCS) has no additional information on CGCS 139 at present.
