What Have I Got? (leica carrying case)

[Arthur Wouk <awouk@nilenet.com>]

i have a leather hard case: 7.75" x 9.25" (top cover) x 2.75" h
the top has the usual leather hinge and a carrying strap is attached
to the top near the hinge and goes through small ports attached to the
box to give a stable carrying position.

on the cover there is an imprint, possibly earlier gold filled, which
says 'Leitz' above 'Leica. in the script style with the underline
flourish. on the bottom there is an imprint: germany.

when i open it, i see what looks like two positions for lenses, with
leather straps to fix the lens in position, probably a 135mm and
a 90mm. in the remaining space there are what are clearly slots which
carry filters, ten of them, a built up section which seems likely to
have carried three rolls of film, and next to it another one which has
a single larger excavated cylinder, and  two built up sections which
are scooped out to accept the rounded lower half of cylindric unknown 
objects, possibly sunshades. lastly, there are two small metal spring
metal shapes which would accept a small rod and keep it from moving
(it would snap in).

there is no way that a leica body would fit anywhere in theis case.

so, what is it?
