Early Oilcan, First Style "Ball behind
c. 1898 -
The earliest model oilcan had a cast brass base with the serial # stamped into the
lower lip of the base. Equipped
with Flat-back transmitter, early brass-bottomed
receiver marked Stromberg & Carlson.
Shown here is an 1894
Stromberg & Carlson Receiver. This is the earliest style of
the SC brass bottom receiver and is very rare. Rather than
having the normal Stromberg-Carlson stamped into the outside
edge of the brass bottom, it is stamped Stromberg & Carlson.
It would have been used on very early SC models, likely much
earlier than this Oilcan. I think they are very interesting.
Note: The diaphragm
adjustment for this receiver is done by using a key to turn
the square peg located inside the receiver. On all
subsequent models, the adjustment was made by turning the
knurled adjusting band located on the outside of the
Early Oilcan "Ball Behind Transmitter"
|c. 1899 - Very similar to the first model with the
exception of the spun brass base, which was less expensive
to produce as well as being much thinner. The thin base
required the relocation of the stamped serial # to the
collar above the base. This model, for reasons I can only
assume, had the number stamped into the spun base. It could
have been produced during the transition, a test model, or
prototype of some sort.
One of the characteristics of
models with the spun base is the development of stress
cracks as they age, which are visible in the close-up. If
desired, they can be repaired.

c. 1899 - Very similar to first
model except change to a spun brass base and serial #
stamped in collar at bottom of tapered shaft. Flat-back
transmitter, early brass-bottomed receiver marked Stromberg
Stromberg Carlson Telephone Mfg. Co. Model
- I display this small wood
wall phone because it is unique and the wood in such
wonderful original condition. The entire rear compartment
houses a large condenser. As do the oilcans during the same
time period, it has the ball behind transmitter type mount
that seems to be specific to this application. There is
possibly another similar SC wood phone as I have an
additional mount and transmitter where the mounting holes
are spaced slightly different not allowing it to fit on this
