      AUTOMATIC ELECTRIC DIAL CANDLESTICK TELEPHONE
      This is the first automatic dial telephone, invented around 1905.  With its 11-digit dial,
      customers could call directly without going through an operator.  The inventor, Almon
      Strowger, was an undertaker in Kansas City in the late 1800s.  The wife of his only
      competitor worked the switchboard at the local telephone exchange and when a caller
      asked for Strowger, she would put the call through to her husband.  After years of
      complaining, Strowger developed the first automatic telephone switch out of
      electromagnets and hat pins.  On November 3, 1892, the first Strowger exchange was
      opened for public service with about seventy-five subscribers.  When his system made its debut, Strowger bragged that his exchanges were "girl-less", "cuss-less", "out-of-order-less" and "wait-less".  This particular telephone was made by the Automatic Electric Company.

CHICAGO TANDEM GLASS FRONT TELEPHONE
Circa 1906, this two box telephone was manufactured by the Chicago Telephone Supply
Co. in Elkhart, Indiana.  The top portion contains the bells, magneto and necessary
wiring to make it work while the bottom houses two shelves that held the batteries. 

Known as a bridging telephone, this six-bar phone has the Chicago genuine solid back
long distance transmitter and was guaranteed to ring more bells than any telephone produced by other factories, transmit speech better and farther than any other
telephone, and outlast any other telephone.  These statements were backed by the
factory guarantee, which was "as good as a government bond.”

      CALCULAGRAPH
        Circa early 1900s, the Calculagraph is a device which mechanically
        calculates and prints the elapsed time between two events.  Originally used
        as a means of tracking table usage in pool halls, they later became the
        standard way to clock the duration of long distance telephone calls.

        While the call was in progress, the toll ticket was stored temporarily in a
        slot in the key shelf associated with the cord pair on which the call was 
        being completed.  That way, the operator knew quickly which toll ticket to
        slip into the Calculagraph and pull the handle when the call was
        completed.  Accuracy depended on the operator being very prompt in
        stamping the ticket when the conversation began and when it terminated. 
        It was only as accurate as the operator was fast. 

        The unit consists of a clock and a precision gear-based set of three printing
        wheels, which print on standardized accounting tickets.  One of the wheels
        presents a clock face and indicates the time at which the call began.  It is
        printed by pushing forward on the right handle.  Pulling back on that same
        handle prints a pair of hollow dial faces with quantities printed around the
        outside.  The ticket is then removed and set aside until the call is completed
        at which time the ticket is re-inserted into the Calculagraph and the left handle is pulled back.  This prints a pair of arrow indicators in the center of each previously printed dial, pointing at the elapsed time since the call began.  The center of each arrow contains a legend.

1904 WORLD'S FAIR TELEPHONE CHART
Distributed at the 1904 St. Louis World's Fair by The Bell Telephone Company of Missouri, this chart      lists the current residence rate of $3.00 per month for a Direct Line and $2.00 per month for a Duplex (two party) Line.  In today's dollars, the cost for a monthly Direct Line would be about $85.69 and the Duplex Line would be about $57.12.

Unfolded, this chart measures 18 yards, or 54 feet long and lists the exchange, number and first and last names of residential subscribers in alphabetical order.  The estimated growth for 1905 was about 10 yards more!

WESTERN ELECTRIC MODEL 302
The Western Electric Model 302 was the first telephone to include the ringer and network wiring in the same desktop phone.  The majority of the Model 302 telephones were black and had dials with metal finger wheels.  Colors became available starting in 1939 for those who were willing to pay extra for the color.
 
Housings were originally made of zinc alloy, but gradually changed around 1941 to thermoplastic sets which were available in ivory, Pekin red, green, blue and rose and had plastic finger wheels.  Production was suspended due to WWII but resumed in 1945 with black plastic housings and by 1949 color sets were again being offered.

     BELL SYSTEM CABLE CAR
      In the construction and maintenance of aerial cable, it was necessary to work along
      the supporting strand so a small trolley-like vehicle called a "cable car" was
      used.   It  consisted of a light, steel frame mounted on two rubber-tired wheels and  
      supported a wooden seat by means of short chains and snap hooks.  The height of
      the seat could be adjusted by the technician by shortening or lengthening the
      chains.  A strap was threaded through the D-ring in the workman's belt and was
      attached to the eyelets below the wheels to protect him from falling.

CHARLIE THE TUNA
Circa 1987, this one-piece touch tone telephone depicts the cartoon mascot Charlie The Tuna. 

Charlie is the spokes-tuna for the Star-Kist brand of tuna and believes he is so hip and cultured that he has "good taste" which makes him the perfect tuna for the brand.

Features include tone/pulse switchable, hook switch and dial pad on the bottom of the phone, one piece construction, last number redial and ringer on/off switch.

U.S. NAVY ROTARY DIAL TYPE G TELEPHONE
This Type G rotary dial telephone was made for the Navy by Dynalec Corp. and is one of the few companies that still supply sound-powered telephones to the Navy and private ship owners today.  

Type G phones were used in all new dial telephone system installations to replace the type A (desk phones), C (splash-proof), and F (bulkhead) telephones as they wore out.

The box is made of heavy gauge steel with a stainless steel face plate and a baked-on orange enamel plaque identifying the telephone manufacturer and that is was ordered by the Naval Sea Systems Command. 

A sticker on the handset reads “DO NOT DISCUSS CLASSIFIED INFORMATION.  THIS TELEPHONE IS SUBJECT TO MONITORING AT ALL TIMES.  USE OF THIS TELEPHONE CONSTITUTES CONSENT TO MONITORING.”   The handset “snaps” in place using a pin which secures the handset to the box when not in use.
