I haven’t got the crankcase apart yet, however Anthony Parker took some nice close-ups of some of the damage, which are in a folder. I’m not sure if I can share the link, but I’ll figure it out. Dave D

Thanks for the update, Dave. Were you able to find the bolt halves in the sump?  If so, and it is not too much trouble, could you post a close up of the failed face of the bolts. I would be interested in having a look to determine whether it was fatigue failure or catastrophic.

Here's what's going on with my engine. I've removed the head and see evidence of possible connecting rod bolt failure, but won't be sure until I can get the case apart and look around. I'll be buying another Revmaster because it is the fastest way to get back in the air.
