Mizpah Scottish Brooch

I popped round to the local shops this afternoon, to get some tea, and of course I had to see what the charity shop had to offer. I came home with this lovely Scottish Brooch, which is marked Mizpah. After a bit of research I discovered these brooches are made by Miracle is
which is the trade name of A. Hill & Company Ltd. of Birmingham, England, which started manufacturing jewelry in 1946. Mizpah is one of the many trading names used by this company. I've realised I have another Mizpah brooch, and the much larger Sol D'or Miracle brooch, all made by the same company.
