Maybe not much help, but I did repair a mechanical Waralarm once.
It had what appeared to be some sort of papier-mache case, and the UK 'Utility' symbol stamped on it, so it will have been made as a cheap clock in the WW2 period, or soon after.
It had what appeared to be a Westclox movement -the sort with cast pillars and arbors, with steel cores for pivots
I too have a mechanical clock with the words "War Alarm" on the dial. On the bottom of the dial is printed, "Made In LA Salle, Ill. USA". On the back is stamped "Maximum Price $1.65 Exclusive of Taxes.
Thank you both for your replies.
Mike, the clock you speak of was indeed a Westclox and used a non-metal case as you describe. Saving metal and all that. Later they went back to metal cases as Greg writes of.
Greg, The price you write of was because we became something of a "Command Economy" during WW2. Prices were controlled by the government to prevent gouging due to limited supplies of consumer goods because of war production needs.
BUT... what I really want to know about is the ELECTRIC Waralarm not the wind-up Waralarm.
