These are with double O-O getter, brown base, and welded plates. I have total 35 tubes and will match a quartet or two. Mullard Blackburn, 1957, December, week 4. I will be able to match one or two quartet`s very close.
Damn this guy found 35 pieces of OO getter Mullards, new in box, and is selling a quad. Holy grail tubes. Will not be cheap
