The  » AVIAT 615 «  is made of plastic  and came in a black round
leather case - Unfortunately the manual was lost - BUT...

The several  »AVIAT«  models are different by the methods used to
solve  "Triangle Problems" ( and in the AVIATJET the air speed ).
Models 613, 617 &  AVIATJET  use simple, strait-forward graphical
solutions, like the  AVIAT-618.  Models  610  & 615  use the sine
rule to obtain  strictly mathematical solutions.  Model  610 is a
smaller version of  Model 615 ( = 14 cm Diameter ) and  Model 613
is a pocket-size version of the  Model 617.
