(1)The first, is a large Columbia reproducer with an embossed copper(?) disc where the diaphragm normally goes. It is called a "Concert-Tone" - World's Best Tone Sounding Device, patented by Harry H. Thompson, Kansas City, MO. It appears to be some type of volume enhancing or reducing device...

(2)The second, is a "RADIO" Trade Mark reproducer made by the Crippen Co. of New York City. It has a strange metal bar attached to the face, that encloses a wooden "bridge" with felt pads that touch the diaphragm. The tension on the bar can be regulated by a knurled screw that applies or releases pressure on the diaphragm. This also appears to be some type of volume control or sound modification device. The tonearm connection on the back exits upward, so it is hard to imagine what type of tonearm it was made for. What machine did this go to, or was it an after market reproducer? It had to be made for some specific machine that had a corresponding tonearm... It looks like it would work on my Fairy Phonograph Lamp...
Any information regarding these would be helpful, since I cannot find anything about either one of these...
