Apparently, Ukraine isn't the only country that attempted to
make a 120mm NATO derivative of Eastern-bloc tank gun.
(PRC doesn't count, since their 120mm gun is a derivative of the Rheinmetall L/44.)
I've only been able to find pictures for the manually-loaded M-393 designed for T-62, but what interests me is the M-395 that's designed for T-72. I wonder if the gun still uses a carousel autoloader......
The story also reminds me something I heard online about Russian once attempted to compete for British MBT programme with a version of T-90......
(Actually, Rickshaw, is that you whom I heard it from? Do you have further information on it?)

Oh and Merry Christmas for everyone who celebrates Christmas, and Happy Winter Solstice for everyone who doesn't.
