   Yes, I have checked the both (the latter reference should be its
"Supplement").  The outburst statistics mentioned in the previous message
was from the latter reference.  The former reference has been checked
during my previous study of precise coordinates of variable stars.

   However, I remember I have seen (but don't remember the bibliographic
data) an (old) AN? reference that showed a chart with the galaxy.  Although
the maximum in GCVS apparently took over Kolotovkina's value, the maximum
recorded in the AN? reference was much brighter (around 13?).

   Perhaps this suggests that frequent visitors to CP Dra may have a better
chance to discover a SN than to watch other field dwarf novae ;-).
