LOC-NOB refers to the pair of ears on a Dietz lantern globe used to keep the globe from falling out when tilting the globe plate for lighting or trimming the wick.  LOC-NOB globes were first offered in the 1917  Dietz catalog, (There are three patent dates associated with the LOC-NOB design, 3/10/14, 2/18/18 and 12/4/23,) and eventually became the standard for most all Dietz lantern models.  The first "LOC-NOB" style globes were made in 1915 and marked "NOBLOC" in the D-Lite/Wizard size only.  It is unknown if this was a mistake made by the globe manufacturer and was quickly corrected, or if the original name was to be "NOBLOC" and was changed to LOC-NOB for some reason. (NOBLOC could be mispronounced as ("No Bloc.") There were not many "NOBLOC" globes made, and that the only known examples are clear.  The first LOC-NOB Fitzall globes were made after 1918.  (The introduction of the LOC-NOB style globe coincides with the transition period after John E. Dietz assumed the reins of the company after his elder brother Fred passed away April 3, 1915.)   The alpha-numeric code (such as "H8") found on most Dietz lantern globes made before 1956 designates the manufacturer and mold number.  Here are the codes:    "A" = Anchor (Pre-1937) "C" = Corning "CNX" Corning No-Nex (Fore-Runner to Pyrex) "CR" = Crescent "G" = Gleason "H" = Hocking (After 1937 Anchor Hocking) "J" = Jeanette "L"=Libby "McK" = McKee "R" = Rodefer
