I need the knob shown in this photo as the MODE switch knob. It's the same knob as used on many small Heath Accessories and rigs of the era: http://www.pestingers.net/images/Heathkit_radio_equipment/HW5400/DSCF0101.JPG Will pay reasonable price and shipping in a padded envelope. Thank you for any help and Merry Christmas John K5MO
