eg Finland placed those on T55 platform and nowadays installed on 2a4 platforms.
Another example: Poles have the PZA Loara which is on twardy platform (in essence further development of T72).
Japanese version is Mitsubishi type 87.
There will be market for the ammunition, and more guns for surplus platforms, if proven efficient.
Poland has developed its own 35mm programable ammunition. The latest version of the gun is the
AG-35 a shipboard version has already been installed
