The resistors the same type as Philcos from 20/70/90, with metal (tin-led) ends barrel-shaped ending with cones.
The color code is likely proprietary or at least it is not your "Bad boys...." thing as "Red+Blue" means 100K, "Red+Yellow" - 250K, "Blue+Grey" - 1M etc.
there are 4 flex resistors under the chassis and also some under RF chassis.
One (670 Ohm) is missing and replaced with a wire (green cloth covered), and one (2kOhm) is replaced with a regular longish carbon resistor (which is well within specs) and tied to a different physical spot on the same signal, plus some other things like a broken solder lug on the band switch nearby where the resistors are soldered to, from which I make an assumption it was at some point repaired. The remaining flexes are dead on, probably wire-wound.
Some old carbon ones are remarkably close to the nominal value.
Here is a question I have:

Does anyone know if the C6 quad capacitor is paper or mica? It looks like a paper (a large block of four caps) but the values and the place it is used imply possible mica type.
I am not sure this will be changed (this is oscillator circuit grid feedback so it is low volts, no problems with possible shorting) and the values seem to be not too far from the nominal, but would like to know for my own peace of mind.
