In addition, the word "Westclox" was lettered in two ways. "Small Westclox" has all the letters of the word "Westclox" in capital letters, all the same height. In the "Large Westclox" type, the "W" is upper case and the other letters are lower case. The small "Loud Alarm" and "Small Westclox" were used on the first dials. Then, the "Large Westclox" came into use. Finally, the large "Loud Alarm" replaced the small version. |

Westclox | Big Ben Style 5 Loud | Back Type | These backs have a USA, Canadian, Australian and British patent. The two types are so similar that I didn't record the type for many clocks I had. For completeness I am showing both types here. |
Westclox | Big Ben Style 5 Chime | Back Type | All Ben Ben Style 5 Chime Alarm backs that I've seen have five patent numbers. There MAY be an early back without the design patent number. |

Westclox | Big Ben Style 2 | Base | Big Ben Style 2 bases were made by several companies, including the Dura Company of Toledo, Ohio; and the Doehler Die Casting Company also of Toledo, Ohio. I've seen a few bases having a logo of a diamond with an ampersand inside, but haven't identified the company that logo belonged to. The most common bases have the letter "A" and other markings; and I don't know if Westclox or another company made them. The variations of the bases recorded here are not as significant as other features I've documented, but I found them interesting enough to record. |
Westclox | Big Ben Style 2 | Base Bottom Color | Some are black on the bottom and some are gold. The first nickel clocks are black on the bottom. As far as I know, all painted finish clocks have gold bottom bases. Later nickel clocks have gold bottom bases. |

Westclox | Big Ben Style 2 | Cast Base Metal Condition | The Big Ben Style 2 was an early use of a die cast base by Westclox. Some of these bases are in bad condition, and some are remarkably good. These conditions are a rough way to track how well the bases aged. |
Westclox | Big Ben Style 2 | Number of Base Corners Gone | Sometimes one or both front corners are broken off. This is a rough attempt to track how well the style 2 bases aged. |
Westclox | Big Ben Style 1 and Style 1a | Dial | This series of dials covers Big Ben Styles 1 and 1a. The earliest form of the Style 1 dial has unusual numerals, including a backward-curving leg on the "7". The Big Ben was improved from Style 1 to Style 1a during the period that the dials were made with "Westclox" in italic text. Luminous dials were first made in the Big Ben Style 1a era. |
Westclox | Big Ben Style 1a | Back Type | Style 1a Big Ben clocks have a series of patent sequences on the back. The patents were in two different locations. Later backs have patent numbers instead of dates. |

2) Second type: Minute hand has decorative cap in the center, the sides of the hands are straight (the whole hand tapers from narrow to wide). The short end of the hand is the widest part of the hand.
The standard type (used starting sometime in 1956 to the end of Style 7 production): Minute hand has cap in center, the hand tapers from narrow to widest at the center, then tapers narrower again. The short end of the hand is narrower than the center. |
Westclox | Ben Style 7 | Lens Shape | Pointed lens until 1960, then rounded. |
Westclox | Ben Style 6 | Back Type | Early backs say PAT. PDG., later ones don’t. It is unknown if a patent was actually applied for or why a patent wasn’t pursued. Perhaps the design of Style 6 was too similar to Style 5 and was not considered worth the expenditure to go after a patent. |
Westclox | Ben Style 4 | Luminous Hand Type | On luminous style 4 Baby Ben, the earliest examples have simplified skeleton hands, most examples have solid hands. |
Westclox | Ben Style 2 | "De Luxe" or not | The first Big Ben and Baby Ben Style 2 say "De Luxe" on the dial. During 1930, "De Luxe" was removed. |

Westclox | Baby Ben Style 8 | Number of Set Knobs | Most Style 8 Baby Bens have two set knobs (separate time and alarm setting knobs). Very late examples have a single knob that sets the alarm in the normal (in) position and sets the time when it is pulled out and turned. |
Westclox | Baby Ben Style 8 | Regulator Location | The first Style 8 Baby Bens have the regulator located behind 7:30 on the dial. After a couple years, Westclox rotated the movement in the case, putting the regulator behind 9:00 on the dial. |

Westclox | Baby Ben Style 6 | Base | The lettering on the bottom varies, and some are cut-out and some are solid. It may be that the type 2 cut out base was followed by the type 2 solid base (as in the Style 6 Big Ben), we'll have to get more data to find out. |
Westclox | Baby Ben Style 6 | Base Cavity Number | Lettering "1 A", "2 A" "5 A" or "6 A", or a number 1 through 7 have been observed on the bottom of the bases. Max Schlenker said these are "cavity numbers" to identify the cavity used to cast the base. |
Westclox | Baby Ben Style 6 | Dial | The font of the name "Westclox" |
Westclox | Baby Ben Style 6 | Movement Material | Nickel plated, or brass plates with blue steel bridges. |

Those with back type 4 are unusual - the bezels have the early type paint, and the backs are noticeably more black - very slightly metallic. |
Westclox | Baby Ben Style 4 | Back Material | Most Ivory Style 4 Baby Bens have a steel back which is copper plated then brass plated. A few late ones have a back which is nickel plated then lacquered pale gold. |
Westclox | Baby Ben Style 4 | Base | Very early style 4 Baby Bens say "61L" on the base, most say "61N". |
