Vintage Honeywell Tap Alarm Home Protector System Very Rare Item

This item comes in heavy duty carrying case but case is in poor condition. The honeywell alarm is in very good condition and was tested and works but can not gtarantee that everything works. Push on front Honeywell Button and bell does ring. Flip switch on back of machine and alarm goes off. Thats what works. Three buttons in back of system do nothing. Very rare item. Maybe be the only one of its kind left. This item is 100% all original. There was no date on item but looks like the 1950's to me.The systemitself is in very good condition. Heavy duty item and the bell is loud but alarm not as loud. Plugs into 120v outlet. Power cord in very good condition. I think it was stored in the carryiing case that protected item a lot of years.
