Anybody detail the ends of lionel heavyweights?

Ben,

Look here at Mike's OK Engines passenger cars:

Seems like he added the anti-rattle bars to his ends, but not sure if they were Lionel ends or K-Line ends (maybe have been homemade).

Hand brakes on heavy-weight (and light-weight) passenger cars were located inside the vestibule on one end. 

The exception was if the car had blind ends (no vesitubles), such as a diner, lounge, RPO or baggage car. Then there would be an exterior hand brake on one end as well as another hand brake joined with it inside on the opposite side of the car's end wall.
