The viewers pictured below would, at first glance,
easily be mistaken for a Sawyers Model C, however, closer inspection
reveals that it is a TELE-VISEX, manufactured by Alto-Relevo in Brazil in
the 1950's and carrying the patent number 213133. It's construction was
from bakelite. The viewer weighed in at 220g, against the Sawyers
Model C's weight of 188g.
Whilst clones of
viewers are often inferior to the model they were copied from, this
particular viewer had a major advantage over the Model C, in that it's
body was held together by a set of four screw and nuts. This allowed the
viewer to be opened in the event that dust had entered the viewer and it
required cleaning. The address of the manufacturer was
Floriano Scattolin & Irmãos
Avenida São João 25 - São Paulo Industria Brasileira.
