1j29b-v (1j29b-v) 

Also known as 1ZH29b-v, 1sh29b-v and properly 1Ж29Б-В

There is also 1j29b (1Ж29Б) and 1j29-r (1Ж29Б-Р)

Useful information on these kinds of sub-miniature Rod Pentode tubes (valves):

The 1j29b (all versions) is  still (2011) readily available to purchase as New Old Stock (NOS).

1j29b-v longer life, durability 

The cyrillic suffix -B (v in latin/english) indicates longer life / more durable

The cyrillic suffix -Р (r in latin/english) indicates longest life / most durable / most reliable.

The 1j29b-v (aka 1sh29b-v and properly 1Ж29Б-В) seems physically identical to the normal 1j29b (1Ж29Б) .   The 1j29-r (1Ж29Б-Р) is a different pin / wiring connection.
