Vintage Chain Burglar Alarm . British Design For Your Protection

Vintage Chain Burglar Alarm No. 240 With Original Box The box has been opened, but the alarm is sealed in its original plastic packaging. There is some light wear to the exterior of the box from storage. Alarm only - does not come with a door chain. Please note that this item takes batteries, and because it is sealed I am unable to check them - the device may not come with batteries, or the batteries may be dead.
