Hi Dave , just so you know , If the resistor I have (as a display model only) was any good I'd have offered to send it to you for your project , but it is defective in that it doesn't vary the resistance smoothly . Pulling/pushing the plunger with an ohmmeter attached shows the meter's needle fluctuating excessively like the classic dirty potentiometer , just what you don't need in your grid leak circuit .
