On the National Register of Historic Places, the Old Montana Prison was built by inmate labor and was home to at least one member of Butch Cassidy's "Wild Bunch". Iron bars slammed shut and locked for the first time on July 2, 1871. Emptied of prisoners in the late 1970s, the buildings stand now as silent sentinels to justice.
Jim's parents were getting rid of this little twin pull out couch. I absolutely love it! Unfortunately, it's usually full of my crap!
Looks like an afterthought, nailed onto the frame near the bottom. The bundle of wires runs up and behind the line jacks at the top.

I believe this is one of the old original switch boards that helped power the local hospital many years ago in Marlborough... but I'll stand being corrected?
“After the fall of France in June 1940, the main North Atlantic convoy routes were diverted around the north of Ireland through the north-western approaches. By late 1940, the location of the Combined Operations headquarters at Plymouth was increasingly awkward and the decision was taken to move the Combined Operations headquarters to Liverpool. On 7 February 1941, the headquarters was established at Derby House, Liverpool, with a secondary control bunker built in Magee College, Derry. The headquarters of No. 15 Group RAF (part of Coastal Command) moved to Liverpool at the same time. On 17 February 1941 Admiral Sir Percy Noble was appointed as the new Commander-in-Chief, Western Approaches Command.
“Over the next two years, Admiral Noble built up the bases for the North Atlantic escort groups at Greenock on the Clyde, Derry and Liverpool and set up the training facilities that were the foundations for eventual victory in the Battle of the Atlantic.
“On 19 November 1942, Admiral Max Horton replaced Admiral Noble; Horton then was Commander-in-Chief until Western Approaches Command closed on 15 August 1945.
“Horton’s leadership played a vital role in the final defeat of the U-boat menace. Horton used the increasing number of escorts that were available to the command to organise ‘support groups’ that were used to reinforce convoys that came under attack. Unlike the regular escort groups, the support groups were not directly responsible for the safety of any particular convoy. This freedom gave them much greater tactical flexibility, allowing the support groups to detach ships to hunt submarines spotted by reconnaissance or picked up by high-frequency direction finding (HF/DF). In situations where the regular escorts would have had to return to their convoy, the support groups were able to persist in hunting a submarine for many hours until it was forced to the surface.”

This is a shot of the underside of the keyshelf. The bundle at the bottom carries wires which correspond to the telephone lines being bridged together by the switchboard.
One switch controls whether or not the operator is in on the conversation on a pair; the other causes either the caller (called ringback) or callee line to be signaled.
A switchboard is usually a low-voltage (240–690V) three-phase board comprising manually functioned molded-case circuit breakers.
Switchgear usually denotes to three-phase mid-voltage electrical gear, fusible disconnects, circuit breakers, etc.
A panelboard is normally a low-voltage single-phase supply panel with one and two-pole circuit breakers.
