Be aware that none of the pages are all inclusive since related information exists on one or many other website pages.For example, there is information pertinent to dating a bottle on virtually every website page.The author created this website as a BLM employee and continues to update and enhance the site in retirement as a volunteer.This website now has a permanent home courtesy of the Society for Historical Archaeology (SHA). This entire website is essentially a "key" - albeit a complex one - to the dating and typing (typology) of historic bottles.Since there were hundreds of thousands of uniquely different bottles produced in the United States (and Canada**) between the late 18th century and the 1950s (Fike 1987), it is beyond the scope or even possibility of this site (or website or book) to provide specific details about more than just a tiny fraction of a percent of that variety of bottles.Even then the bottles discussed in depth are so primarily to illustrate the presented information and concepts.
The decoding is based on the following format (also see chart below): Year Decoder: G = 1990; H = 1991; J = 1992; K = 1993; L= 1994; M= 1995; N= 1996; P= 1997; S= 1998; T= 1999; W= 2000; X= 2001; Y= 2002; Z=2003; A= 2004; B=2005; C=2006; D=2007 Month Decoder: A= JAN; B=FEB; C=MAR; D= APR; E=MAY; F= JUNE; G=JULY; H= AUG; J= SEPT; K=OCT; L= NOV; M= DEC.If you are interested in identifying what a bottle was likely used for - i.e., what "type" of bottle it is (aka "typology") - the Bottle Typing/Diagnostic Shapes page and the extensive array of related sub-pages should be visited.This very large complex of pages includes bottle type specific sub-pages with extensive style based dating information, including complete scans of 5 different early 20th century (1906 to 1933) bottle makers catalogs spanning the mouth-blown to machine-made bottle manufacturing era!Check to see if the installation date is noted on the sticker.If not, then write down your serial number as it usually indicates the year and month of manufacture of the water heater. 1209D1234 (MMYYPnnnn) = December 2009 MM = month of manufacture YY = year of manufacture P = plant identifying code nnnn = a consecutive serial number for your individual unit ex.
