Before I remove it and make an axial scrape along the coating would

know what that value should be ? 3 band accuracy in a pc or is there
some
other convention not ordinary 5 band coding ?

PCs are no different than any other device, resistors are resistors.
Red yellow yellow would be 240k according to my calculations.

But the point is its 5 bands so 24.4 ohms but the third yellow band implies
accuracy between 2.43 and 2.45 ohms but the silver band implies a value
between 22 and 26 ohms or so - illogical as Mr Spock would say
