In the last issue of Tactical and Technical Trends (No. 28, p. 15), the
four known German Tellermines (antitank mines), known as Tellermine Nos. 1, 2, 3,
and 4, were described in some detail. An exterior view of Tellermine No. 4 is now
available, and for purposes of comparison and identification the exterior views of all
four mines are published herewith (see accompanying sketches). The mines are all of
about the same dimensions, being approximately 12 inches in diameter and
from 3 1/2 to 4 inches in over-all height. The relative scale of the 4 mines
is only approximate in the sketches.
It should be noted that the pressure plates on Tellermine No. 1 and No. 3 extend
over the entire top of the mines, but the pressure plates on Tellermines No. 2 and
No. 4 cover only the center portion of the mine. Accordingly a tank might pass over
the edge or rim of Tellermines No. 2 or No. 4 without detonating the mines, whereas
the same load passing over the edge or rim of Tellermines No. 1 or No. 3 would
detonate the mine. It is possible for a spread-out load of fairly low intensity covering
the whole top of Tellermines No. 1 or No. 3 to detonate them, while a more
heavy, concentrated load is necessary to detonate Tellermines No. 2 and No. 4.
The pressure plates on Tellermines No. 2 and No. 3 are fluted or grooved, but
the pressure plates on Tellermines No. 1 and No. 4 are smooth.
