Source never saw, heard of, or ha~ any evidence of. a lead sulfide cell's
having been produced at Zavod 393. In the laboratory of Dr. Goerlich,
source saw what'he took for several lead sulfide cells in various stages
of construction. He emphasized that.theee were experimental cells, if
they were'PbS'cell's. They were double walled glass containers about 12
to 14 em long." The inner tube.'was about 2 cm in diameter, while the outer
one'was"3'to 3.5' cm in diameter.., There was a Dewar seal at one and. An
electrical conducting strip was painted along either the inner or outer
wall of the inside tube, ending'at an electrical lead at what source
assumes was; to be the upper end There'was a second electrical lead at
this end`, but source does not recall how it was connected or the exact
location. The lower end, or flat surface, of the'outer tube was opaque
with a'square, clear window about'10 mm on'a side. The lower and of the
inner-'tube'was coated with a substance which source says was PbS. He
drleernnot owSwhether the PbS was on, the inside or outside of the ., .

with an aebestos'eylinder containing a`heating element. They were baked
at 650? for 20 minutes. These were experimental cells and not production
cells. Source never saw a completed cell and cannot say'whether either
a #'bS experimental or production cell ever was completed.
