REPLACEMENT/REPRODUCTION 1910 COLUMBIA #6 DRY CELL WAX SEAL

Description

The unit for sale is a reproduction of an early version #6 dry cell battery produced by the National Carbon Company (NCC) with the Columbia label and Patent date of 1910.
NCC introduced the first commercially produced #6 dry cells around 1896, and was the sole source of dry cells for farm and home uses, the auto industry, and telephone companies in the early 1900s.
In the early years of production of the #6 dry cells, the negative terminals were 8-32 screw binding post type, and the center terminals were on an extended carbon slab post.
Original manufacture of these phones included spaded battery leads.
To meet increasing telephony demand the Western Electric Company (WE) began producing dry cells with its'
Blue Bell label for the Bell System Companies around 1907.  After 1907, NCC remained as the primary source of #6 dry cells for the non-Bell phone companies, and an additional source for Bell System until at least the 1900 mid-teens.
So
i
f you have a single box wood wall phone of any manufacturer (other than Western Electric) produced between 1910 and 1922, this reproduction dry cell could be historically correct for display inside.  Another Columbia label was introduced in 1923, and a reproduction of this version is also listed on my Ebay page.
My dry cell reproductions are configured to produce 1.5V each with two D-Cell battery holders (wired in parallel), and feature
top access
to allow easy replacement of the batteries (not included) when necessary.
Dry cell d
imensions (7-1/8”H X 2-5/8” Dia.), weight (2 lbs. W/D-Cells), label graphics and colors are nominally consistent with the original battery of this era equipped with the carbon slab center terminal.
The tops are potted with
sealing wax (over
epoxy)
which is similar in appearance to Pitch which was used in the original production
.
Additional Columbia 1910 units will be produced upon request
