Wheelock A4-H?

I’m assuming this is the correct place for this type of post.

So I was snooping around on eBay and I saw an alarm for sale titled “Wheelock A4-H”. Of course I was intrigued because I’ve never seen this model # before. This is what it looks like:

So is this an actual alarm? I have never seen this alarm in my life. Could this be another example of an unheard of Wheelock alarm (hinting toward the Wheelock 32P that WheelockAlarms has/had)?

That’s a Space Age HA24D horn that the eBay seller mislabeled. I don’t think a Wheelock A4-H exists.

Oh wow :lol: thanks
