Not sure what you mean by "spacer bar at the base of the digit", but you should move the tube around and observe if there are any sounds coming from it while you rotate it. I have one IN-14 tube in which the decimal point "cathode" has ripped off and is moving inside the tube freely...also, the small metal parts are sometimes used to attach the "shadow paper" on the back of the tube. In such case, it might be possible for the metal piece for short the digit and the anode (not necessarily the digit cathode to the anode mash if it's not the first digit stacked, but perhaps the wires below the mica/plastic disk)..this would result in anode and the shorted cathode to be on the same potential, thus not igniting the digit.
