Dieter, I have just looked in the Electronic Tubes and Semiconductor
Elements Universal Vade Mecum vol 1 by Piotr Mikolajczyk, 1960 and quite a
few are listed.
BTW, a lot of the book is also at Frank's site:-
http://www.tubedata.org/
Just to check... these are tubes for radio etc, not Nixies?
The book gives A-110 as nearly A-109. Is it a 4-pin valve/tube? If so, the
group of three is filament at the outsides and grid in middle. Pin on its
own is anode.
Are DK31 and DK32 both 8-pins and top-cap? Frequency converters.
If these details match your tubes then I can sned you scans/photographs of
the base pin-out and data etc.
I also have various tube-tester handbooks.
