I must say that I collected these little mini-oilers since the 1970's, and seldom found one of these.
Dictaphone's (originally spelled "Dictaphon") roots go back to pre-1900 inventions by Alexander Graham Bell. The name Dictaphone was trademarked by one of his successor companies in 1907.
This all-original oiling can is embossed "DICTAPHONOIL". It stands about 4-1/2" high. No rust, no dents. Very good condition overall.
The price is $25, plus the shipping. Thanks for looking. John
