I obtained a rather nice cast lens bord for the
shutter/lens within it. The casting number 105822 in
two places one just above the other. It is probably
off-shore and has expertly opened up to US "3" small
for the Wollensak mounting system. It is almost
exactly 1/32' less than 4" square and is 3/16" thick
from face to rear of baffle. Is it a user or junker?
