Just replaced the gas valve thinking that was the source of the problem causing the oven not to light when in the Bake function. Bake function still inoperative with new valve. The function select and thermostat controls are functioning correctly. The Bake glo plug lights, however, I notice that the glow on the bake glo plug seems to be concentrated at the center of the plug, whereas the glo plug for the Broil function seems to be illuminated along the whole length of the plug. Would it be correct to assume that the Bake glo plug may not be producing sufficient heat to trip the gas valve and that a new glo plug is required? (Correction on the Model Number: RSS-380 instead of RSS-388)

Well done. Except for the unnecessary expense of a gas valve, I'm glad you were able to solve your problem.
