I would not try to re-use a resistor pulled from a radio, especially a BED coded dogbone style resistor with radial leads. Even if it tested good the weak point in those resistors is the connection between the carbon composition rod that makes up the body of the resistor and the leads. The leads are just wrapped around the rod and over time the wrap can loose contact, removing the resistor by moving the leads around makes this even more likely. I believe that this is the reason so many of those dogbone resistors drift so much in value so much worse then then molded types that succeeded them.
If you like the look of the old style resistors I would try duplicating them through Steve Davis's method, modern resistor, plastic tube, solid buss wire, and paint.
