It is possible to pump a CRT without baking. This was done for the 6/6 rebuild at Display Electronics in 1986. They gave 2 reasons. One was worries about the state of the pyrex, fears that it might implode due to all the imperfections in the glass. The other was the purely practical point that the CRT was too long for their oven.

The CRT worked very well after rebuild but I don't know how it's doing a few years on. The set with this CRT is currently in store at the National Media Museum, Bradford.

I know that the CRT wasn't left down to air for very long. While the gun was away for rebuilding they fitted the graded seal and rough pumped it. They also fitted a generous amount of getter.
