No - I admit I have not heard of the Ravin. No brownie points there.
I knew two Comanche pilots who have flown the aircraft across the Atlantic. One was the venerable Mike Dible who flew the Newfoundland to Azores route in the late 1960's (there was an article about this in Pilot magazine at the time). Mike was later seen flying around the UK in Martin Baker's lovely DC3 with John Fifield.
Second Atlantic voyager was Peter Riggs in N26634, a PA24 260 with 10 hours endurance. Peter sadly passed away last year - I know not what happened to this aircraft.
