This is a US Navy free balloon as used for initial lighter-than-air training during the 1920s to 1940s. It is fairly representative for a type of aircraft that first flew in 1783 and soon afterwards found a shape and construction that it retained (almost) to this day.

Handling instructions

The ZF Navy free balloon with the envelope shader enabled.
