Please check your junk email or maybe there is an issue with your mail server. Here is an answer to your questions:
Does the radiotechnique 12at7 have this flavor or sound? - Yes, following does,

For Brighter and neutral sound, Siemens 3-Mica is better. These came in 100pcs boxes (see all pictures)

You can pay more for the same tube that came in boxes
http://www.tubemonger.com/Siemens_Halske_1960s_3_MICA_E81CC_Munich_ECC81_p/629m.htm
Both of the above Siemens are identical.
Brimars are rich in British midrange but not on the bright side. Our best Brimars are:

Brimars originally came in 100 pcs Military packs (see all the pictures in the above listing). We have packed these in generic white boxes after attaching the bases.

"We have packed these in generic white boxes after attaching the bases."What can you tell me about the bases?
While I have you here, will you look at this old thread in the link and tell me if you have any information for me?
Thanks.

Few years ago, when supplies of premium tubes was depleting, we found a huge stash of premium grade Brimar (ECC83, ECC82, ECC81, 6X4WA) /Mullard (ECC83, E188CC, EF86) /Genalex (EF86, 6X4WA) flying leads tubes.
We then went to work on a simple plug and play solution. It took about a year of various prototypes (some ugly and unreliable). Final version is what you see in the pictures.
Solution included making pins that are like pipes with holes through them. We found an outfit that machines parts for wrist watches and they were able to create such pins.
Flying leads are straightened, cleaned and then threaded through these holes. Leads are trimmed, followed by a solder bath for perfect fusion. Once attached, you cannot separate the base. It is very solid and works as if it is part of the tube.
Lower part of the base is also used in our socket savers.
As for the 12BH7, we have never see this before. ecline6 seems to have the best guess.
I never knew there was such a thing as 9 pin miniature tubes with flying leads.
You came up with a great solution.
Thanks

We were aware of the flying leads tubes but it was great to find large, untouched lot.
Most of these are Royal Naval Store Depot Copenacre Wilts stock - http://www.gazetteandherald.co.uk/news/headlines/nostalgia/2414389.Life_in_a_secret_city/
and S.I.D, R.E.M.E Donnington stock - http://british-army-units1945on.co.uk/royal-electrical-and-mechanical-engineers/central-and-base-workshops.html
Another surprise was to find very early samples from 1950s and 1960s

"No Guarantee Future Supply" - how prophetic *that* was!
Nice job adding on the new bases!
