[Boatanchors] Hammarlund HQ-129X BFO Components Question?

Roger,
I have both the original Operating Instruction/Manual and the Rider book
 on the HQ-129X.  Both show that R46 is a 50K, BUT C43 is only listed as a
"Silver Mica" part of Z1 BFO Assy.  Not much help there.

I'm reassembling a HQ-129X where the BFO assembly was taken apart by the
previous owner.

Fortunately the inductor L30, the variable C45 and fixed cap C44 are all
there and I think I have it figured out where the wires from V9 pins 3 and 4
attach, however R46 which on the schematic looks to be 3K though the parts
list reads 50K, and C43 listed only as a silver mica are both missing.

Would anyone have the value of C43 and confirm that R46 is indeed 50K?

Thanks, Roger, NJ2R
