The classic case exists in two countries Hungary and Brazil.

In Hungary we have two versions for the Hiradastechnika company.
They are very closed to the Sharp but with some differences.

For the PTA-4000 the color is between brown and orange and the plastic fell low-cost.

And the inside zone delimiters are only welded at the bottom, nothing on the sides.

For the PTA-4000+16 it’s the classic brown color

With the same problem for the separators

And here are the two in the same pictures :

For Brazil it a luxurious case, like a jewel case ! My preferred !

There is a special compartment for a memory module.
