Some baffle-piston engines have their ports multi-bridged...
Actually. all baffled-piston ringed engines have multiple ports and unpinned rings which definitely rotate as the engine is running.
Most maybe, but not all, Brian.

See this photo of this baffle-piston McCoys, stated to be ringed (I specified 'ringed' as part of the search).
