I am looking for the specs on the above number. I have looked and not
found anything on the net and nothing is in my manuals. Does anyone
have the specs on this number? Thanks.

A mystery tube.
Nothing in Babani, AVO, RTT, MK tube handbook, Essential
Characteristics, Frank's page. Nothing!

Are you sure this isn't a production run number? What else is on
there? What does it look like, inside and out? Base?

I do not know if it was a production number. I do know it is listed in
the Antique catalogue and a few people have them for sale on the
internet. From what one seller said, it is a signal triode with a
7-pin minature base with a heater voltage of 6,3 volts. What I have
told you is all I have been able to find out. I may have attempt to
get the specs by testing parameters.

I have one 2033, but haven't stuck it in the tube tester to determine
the pinout... It must be common cathode like the 6J6, with only 7
pins. You can get some cheap at HouseOfTubes.com, Richardson's web
outlet.

I made a mistake on the inside of the valve. It is a dual triode like
a 6J6 but does not look like one with the plates in the same
arrangement.

So it could be something like 12DW7 or so, but with probably common
cathodes.
I'm afraid you'll have to do some measuring :-)
