Awesome VINTAGE Fire Alarm Call-Points

These English-made GEC MCPs are so old they pre-date the requirements for MCPs in NZ to be dual-action (a rule that has been in place for decades). I found three of these in an old building in Wellington - One original, one painted white, and one with modified glass. I am in total amazement that these three MCPs are still here and haven't been replaced with modern "up to code" units.
