This feature was not as useful in the field as had been hoped, however, due to adverse conditions such as weather, dirt and dust, water, etc. In addition, the Model 70 resembled a pistol, thus attracting the attention of snipers (who might assume that a man carrying a pistol was an officer). As a result, use of the Model 70 hand imprinter by field medics was rapidly abandoned (as were most of the Model 70s themselves), and eventually the specification that tags include the locator notch was removed from production orders. Existing stocks of tags were used until depleted, and in the 1960s it was not uncommon for a soldier to be issued one tag with the notch and one tag without. Notched tags are still in production, to satisfy the needs of hobbyists, film production, etc., while the Model 70 imprinter has become a rare collector's item.
