So, I just looked this up in the Philco Changes in Models PDF I have available here:

http://www.philcoradio.com/phorum/showth...hp?tid=215

and I see that on November 1, 1935, the shadow meter on Model 650 was changed to part no. 45-2083. This is the same shadowmeter used soon afterward on the mid-season 1936 Philco models using shadowmeters: 635, 645, 655, 665. The shadow meter was also changed to 45-2083 on Model 680. No mention of a shadow meter change in Model 116.

So...I started looking.

I have a 655 chassis in a 645B cabinet. Oddly enough, it had an older style shadowmeter.

Then I looked inside my late version 116B, which came out in January 1936. Lo and behold, it had the same shadowmeter as Audin photographed above!

And the part number is...(drum roll please)...

45-2083.

Audin, take a look on top of your shadowmeter and tell us if it has a part number ink stamped on it. I would be willing to bet the number, if present, is 45-2083.

Oh, by the way, on Philco sets that received this shadowmeter, the resistor that was formerly connected in parallel with this shadowmeter was removed when the 45-2083 was added.
