[Milsurplus] Wanted: C4 ARN 7 Radio Compass control box in nice shape, also PE-109 inverter

[Boeing377 via Milsurplus]

I have a working C4 box but it is very corroded from years on a fishing boat. Looking for one in much nicer shape. 

Also, where can I find the screw in grain of wheat lamps for this box? They have a knurled black aluminum cap and were used on many control heads and indicators.

Also looking for an PE-109 14 VDC to 115 VAC 400 hz rotary inverter. Used on some RCAF C 47s that had 14 VDC instead of 28 VDC electrical systems. Have one but it's pretty tired, commutator, bearings and brushes very worn. Looking for a newer one.

Thanks,
Mark
