I have a 1968
Globetrotter and on left side wall behind the couch/bed is a lengthwise shelf or board attached with hinges to the wall held up by 2 "L" brackets. Is this original-seems to be. Also, if it is how many hinges on it and was it held in up position with straps-I see 2 snaps. Photos or info would help greatly. This is my last repair to interior woodwork until it becomes functional.
