Chicago Telephone Supply Company "oil can" desk set

This is not extremely rare, but the Chicago "oil can" is still a neat telephone. It got its name for obvious reasons, the base looks like an old fashioned oil can. The other feature of the oil can is the curved perch that holds the transmitter, unique to all Chicago oil can telephones. This one is nickel plated and in excellent original condition. Scan is from a 1928 Chicago catalog.
