Yeah, I've never seen anything on this particular shadowmeter, either. It would appear that it was only in production for a few months. As I posted earlier, I've never seen one except on 1936 model Philcos made after December 1935. The exception is my 91RX chassis, and I am convinced it is a replacement. To clarify what I typed earlier, I *think* I may have seen one or two others on older Philcos, but like the one on my 91RX, I am convinced these were replacements. We know that the earlier shadowmeters look like the ones shown on your site.
