Interesting unit.  I'm glad to be introduced to it here.  If I saw it on Ebay, I would be trying to find the Spirit Of St. Louis tag on it.  I would have never dreamed something as fancy as that would be made for that intended purpose.  I guess such equipment would be in close proximity to someone working the Navy's pursestrings at one time or another.

While "trolling" through the online patent files of the U.S. Patent Office today, I came across the attached patent No. 2,433,295, and obviously recognized it as having been the subject of this string of posts.     The set was invented by Mr. Theodore C., RIEBE of Chicago, IL., and assigned to Automatic Electric Labs of the same city.     The application was filed in November of 1944, and the patent was issued in December of 1947.    It was entitled,  "Loud Speaker Telephone".       For those interested, the patent is attached to this post.
Have a great evening.

The JKL museum used to have a complete setup, but I imagine it was lost in the fire.  They were trying to get it to work.  I don't know if they ever did.  Remco would know.
