Mitchum or Blackburn for the Mullard 6922?

Do Mitchum production and Blackburn production sound different in the Mullard 6922? I believe I once read somewhere that Mitchum made tubes for the military, whereas Blackbutn did not, so, presumably, with better materials and/or tighter tolerances or testing.

Tube code is etched on the bottom side.

I'll look for the other numbers in a while. The tube's fermenting in my dac at the moment and sounds rich, detailed, 3-dimensional and quiet.

Yes, it's IEC Mullard, although the IEC is patchy.
