Lionel 6-52036  TCA 40th National Convention Bay Window Caboose LN OB. This caboose looks new.  When i checked the couplers they open with help but do not pop open like some couplers do.  They stay closed when closed.  I think this is due to them being stored in a closed position all these years.  The box also looks new.  The window plastic is smooth.  The crinkled look in the pictures is the plastic bag around the car inside.  The car includes the original lamp replacement paperwork and the lionel service station paperwork.
