[Hallicrafters] Hallicrafters PM-23 speaker

[Gerry Steffens]

I have been going through and editing my Hallicrafters pictures and
comparing to my collection.  I have PM-23 units both with and without the
plastic "h" on the front chrome grill as Dachis describes.

However, I also have a couple of speakers which have what appears to be gray
porcelain grills instead of chrome.  Porcelain may not be the correct
material but it displays a resemblance to porcelain.  Dachis makes no
mention of this.  Anyone know the scoop?  When, why or whatever.  I have
never seen one of these with the "h".  I suspect these may have  been made
during WWII when chrome was not generally available for public use like on
vehicles.

Thanks,
Gerry
