Welcome to The Fire Panel Forums!
Oh it is rare, very rare indeed. That is a Notifier BG-1.
That is vintage and very uncommon to see in service in the modern world!! Save that and send it to Old School Fire Alarms!
I saw the pull station at a store in Santa Monica.
Yes that pull station is rare and there very Expensive too , jjinc is selling them for $145 bucks on his eBay page
I’ve never seen it before in a building (I travel quite a bit so if I haven’t seen something used in a building, probably rare). And yep, that’s quite a rare find. Nice!
