Westclox Big Ben Style 1 and 1a Dial Detail Series

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.
