Yep it looks very much like a doorbell. I actually mentioned that in the video. I like the look of it. You are right it does sound like an Edwards horn. But it is a Kobishi. It also reminds me of my Malgard model 1101 FM gas alarm which does have an Edwards horn. This also sounds like the old Honeywell TC49A. I am glad I got one of these. I hope the other 6 units get sold and hopefully to collectors.
Since you said it goes instantly, try testing it against the SA76RS, see which one sounds quicker. SA76RSs are possibly one of the most sensitive ionization detectors ever made that blowing into them sets them off.
That I will definitely do but it will have to be tomorrow as I don't want to disturb my neighbour upstairs. My SA76RS is also sensitive as is so this shall be interesting and I will make a small video when I do this!!!
@@janeaton3417 Wait, were TC49Bs out during Honeywell's 13.4 days? I know they're the AC/DC variant of the TC49A but I thought they were only out during the 4.4 days.

I made a video not long ago with test spray. The SA76RS definitely wins. Give it a look and let me know what you think. :)
@@janeaton3417 I don't think any of them would top the first generation TC49A with that 13.4 microcurie count.
@@Undercoverelevator212-s2n Would that top the first generation TC49B?? Mine is also a rare contractor model with a cover from 1977 but is dated 1978.
