I got my74 boler
in original condition years ago.
The counter had a furnace
, a little fridge
, sink, 2 burner stove mounted and a silverware drawer.
The electrial came in the side to a receptical box and was
spliced out to the fluorescent and fridge
for the appliances ran along the frame and was spliced up through the floor at the different locations.
The only "shelf" was the top of the wheelwell.
Hope this helps.
