Vintage Nightwatchman Trip String Burglar Alarm

Early Vintage Nightwatchman Trip String Burglar Alarm from the 1950's-1960's.   Very loud horn on this unique alarm that is in excellent condition.  Original instructions still attached to the handle. 

Eight foot electrical cord that is retractable into the case.   The string trip wire is 18 feet long and also retracts back into the case.  On one end is an electrical double outlet for other appliances or fixtures you might want nearby.  On the other end is on/off switch and another switch to actuate the horn. 

This case is in excellent condition and Nightwatchman works just great.  The horn, even when people know it is going off, is very loud and can be heard from a good distance away.
