anyone? is cold dark and lonely in this thread. 
I looked at some other 37's and phound philco was all over the map on the 6K7G IF's Many have the cathode straight to ground but some other variations are:
37-602 300 ohms and 0.05 uF
37-604 300 ohms and 0.1 uF
37-620 400 0hms and 0.05 uF (37-630 also)
37-640 700 ohms and 0.25 uF
These are per the Riders prints in book 7
Was Philco Playing with the IF gain for fun or what????
And in a Philco wouldn't it be a IPH?
