Once again improper spelling made research difficult.
From A Lens Collectors's Vade Mecum
Julius Laack Soehne, Curlandstrasse 60, Rathenow, Germany.

Pre-1919.
Pololyt f3.5 75mm 3-glass eg in pairs on Beyerflex 2x75mm
Pololyt Anastigmat 3.9 135mm This was noted at No122,32x on a Certotrop 9x12cm camera

late products (1930's):
Pololyt This was a lower price series than some of the above, and seems to have been suggested for amateur
use.
Pololyt f2.9 20-75mm These were cine lenses.
f3.5 35mm This was on Altix 24x24 c.1940. It was also made in 20-165mm.
f3.9 This was in the 1939 advert, but without details eg of use. It may be an f3.5
slowed down by a shutter.
