1935 Philco 60B, Version 6, Run #11, Oscillator Cap
#1

I'm puzzled over an Aerovox Mica Cap on this set and it's correct value. I attached pictures of the device and the schematic. It is Item #13 across the Oscillator Coil windings, shown on the schematic as a 110pf. The value has remained the same over the range of different Run's.
In the picture, the Part Number appears to be 140-226. Colors across the top, L-R are, White & Green. Colors across the middle, L-R are, Unknown, Black & Red.
On my DVM Capacitance it reads as a 0.00112mf, BUT I don't trust that on old leaky caps. My EICO 950 Capacitance Bridge reads approx. 0.0014mf. Both are reasonably close, however, the schematic states 110pf!! Off by a factor of 10.
So, I think I should keep the original one, since it appears to be OK, or replace it with a new 0.001mf. But 110pf seems to be questionable. The original does not appear to be leaky. And I am not proficient enough to decode the color for the stated capacitance. I couldn't find any references to the Aerovox Part number.
I'm not sure of it's technical purpose, and how critical the value is.
Thoughts on the correct replacement?
