For many decades, mechanical clockwork leaf shutters were made primarily by a company called Copal in Japan in standard sizes used by all the major lens makers. About 15 years ago, they stopped making them, and the backstock of shutters ran out about 6 or 7 years ago. No more fully mechanical leaf shutters.
A couple manufacturers are starting to make electromechanical (vs clockwork) leaf shutters, but they're proprietary, expensive, and not fully standardized or backward compatible.
