The ac coaches in the LHB rake of 22633 34 tvc nzm had oswal exp e ss written on them. Not sure of the specific number but wild guess that these after getting transferred to bbq went as 06013 mas ju special and now as ju pune special and might run as cstm vlnk premium.
Pic-4 looks great when Non-AC and AC LHB coaches are in one frame for comparison... IR has designed AC LHB style main gate windows for Non-AC LHB Coaches too in a vertically elongated rectangular shape with a glass fitted to it unlike in ICF coaches which had a square window with numerous bars and a metal shutter inside ;-)
