[Milsurplus] [Boatanchors] DAG Receiver: What Is This Thing?

[Dennis DuVall]

I have an original DAG-1 and DAG-2 instruction book dated 21 Dec. 1942 and 14 June 1943.  A couple of the included illustrations provide a glimpse of the caps and chains of interest here.
Unfortunately,  no clear views, descriptive information or part numbers of these items are included in the book.
