Photo 2: LBBG sub-adult, August 18 2001, Missouriweg Maasvlakte, the Netherlands. 

As it seems, the near p10 has at least a mirror, but from below, the far wing looks to be lacking this mirror. Bare parts may be in line with  a 4cy LBBG, but the old greater and lesser coverts, pattern on tail-feathers and lower tertials may advocate 3cy. P7-p10 are old, p6 has been shed.
