Your floors are Teak & Holly which was a factory available option. I think the Parquet floors are rather rare. I have never seen one. They might be more prevalent in older CCs. I suspect that where your tool Cabinet is was originally a settee that converted into a set of bunks. The upper bunk would have been hinged at the hull side and dropped down to form the back of the settee. When in the sleeping position it would have been held up by straps. That is the way mine is.
I realize these are very old comments, but, as for the bunk with the support cords and the removed settee? Exactly. Thats what my CC had as well, and BTW, mine had the parquet sole, and it was a 1968...
