This is a Doskocil waterproof camera case with strap. This will seal a 35mm camera against the elements very well (has rubber seals). Little used, super quality (made in Arlington, TX!), and in great condition.
This case is still available. It is large enough to hold just about any SLR camera body (without a lens mounted, unless it's a pancake lens). It should comfortably hold most 35mm rangefinders with reasonably sized normal or short focal length lenses mounted.
The interior indentation is about 5.7" X 3" by 1.5" deep. The total height interior is about 3.5". The internal padding is removable. The external dimensions are about 9" X 5" X 3.5". One can cut and customized ones own foam for this if desired.
If it is still available, I'd like to come see it at least, and probably will purchase it. Friday would probably be best, but I could swing by tomorrow if needed.
