I have added additional images and a pretty high magnification view of an intracisternal protein body in the type II alveolar cell of a guinea pig (Animal 301, aged, Hartley) which was used as a control in some exposure studies.  I think it seems pretty clear (that is a cya statement) that there are two ribosomes positioned just inside the dominant bands in these highly structured protein inclusions (see the last part of this video on youTube).  The dominant bands are spaced just about 0.1 microns apart.   HERE is the link to youtube.

The journal article where the cisternal body is discussed in detail is an “oldie” published in the Journal of Ultrastructure and Molecular Structure Research,  95: 131-141, 1986.
