Part of the unique experience in collecting old Victorian pencils is the ingenious, sometimes unique ways the devices work. Clockwise from the top are five distinctly designed champagne bottle mechanical pencils, each using a different tip deployment method.

From the top is a solid mounted push / pull telescopic
followed by a bottom ring twist activation mechanism
followed by a push / pull activated magic pencil
followed by a button activated gravity based dropper
Center position is a pull out / push in external collapsible

All pieces are silver based metal and were produced circa 1885 - 1895 .
Sizes closed range from 1 3/4 inches to 2 3/4 inches.
