This site first considered the hyphen hole 14 variety on September 19, 2010. Today are two examples sent in by David Thompson, the first an R164p example and the second and RB24p example. Is it possible to find this variety on all the slot perforated battleship stamps?
R164p with HH14 between 3rd and 4th stamps.
RB24p vertical line block of 4 with HH14 running horizontally through the block
