Chicago Manufacturing and Distributing Co. Universal joint and socket

[Northwoods]

Found it in a barn sale today.  Big sucker.  5/8" drive.  Four and three quarters inches long.
U-joint is A 10; the socket is A 19.  It looks to be 15/16".
There is no friction ball on it.  Instead, there is a riveted clip inside the female end of the U-joint.
No rat or other components.  Dang it.
