After I watched the video Baxter posted my system immediately brought up another video about Queen Mary.
For me it raised some more questions, as I have not previously seen the brooch I will refer to below. I hope others have and can provide information.
The video can be seen at https://www.youtube.com/watch?v=OIW7arfuDIw
Views of the brooch I am interested in start at approximately 3.27 minutes. There is a second view of this brooch, on a different occasion, at approximately 3.34 minutes.
Does anyone have information or knowledge about this brooch?
PS When previewing my message, I noticed that the link is not working.
To assist board members, the name of the video on YouTube is "Mary, Queen And Mother (1953)" I apologise for not being able to make the link work. I am not sure why it won't work. When I copied the link into a new window, it worked, so I hope others will be able to view it.
