Standard Telephones (STC) horizontal view nixie with 10 mm. symbols '+', '-' and '~'. On the sample shown here there are only 4 pins, the remaining 3 pins do not protude from the base, although they are present internally. The pin out (pins are numbered clockwise from the gap, looking at the tube from below) is :-

Pin	1	2	3	4	5	6	7
Electrode	a	np	k(-)	np	k(~)	np	k(+)

I have no data for this tube but the characteristics are probably similar to the ZM1081 which has the same symbols :-

"Recommended cathode current is 2 mA. The normal maintaining voltage is 140 V."

This tube was kindly loaned for photography by Dr. Dave Knight. He has an excellent page on nixie tubes.
