None of these further versions got beyond the planning stage.

This effort was much too close to the original to be safe from potential lawsuits, so two further versions were created.

It appears that all further versions, starting from 6.2u6, will be commercial (with a 90-day free trial).

Two prototypes of a further version, for Airborne forces, were made.

This was a further simplified and slightly enlarged version of the M1940.

There are now a number of further versions in museums and cities.

In 2009, a further updated version known as the Bevmax 4 was introduced.

A further improved version, the 2/722, then became the standard issue in late 1971.

A further revised version was submitted in 1928 but rejected again.

A further version was released in 1998, credited to Miss Jane.
