Bob,
Anchor logo with an "H" superimposed over it (shown)........Anchor Hocking Corporation, Lancaster, OH and other plant locations (1937-to date). Although this mark was reportedly discontinued in 1977 in favor of the "new" mark ("anchor within a rectangle" below), I've seen new glassware produced by Anchor Hocking bearing this trademark, so evidently the mark is still in use on some items. For a list of Anchor Hocking plant numbers and other info pertaining to bottle bases in use during the 1960s/1970s period (courtesy of Dick Cole, fruitjar.org), click here . Most of the Anchor Hocking glass container plants were "spun off" in 1983 to form the newly created Anchor Glass Container Corporation. See their anchor logo, pictured farther down on this page.
