Not ringed, the OS .32 SX was ABx.
You could buy a ringed version later on. I had one NIB for a while and it was factory produced as a ringed model. Even said so on the box. Wish I had held onto it now. I can't blame anyone for wanting a .32 SX ringed or non ringed, nor the older model, the .32F and .32F-H. Both terrific engines.
