I saw that helicopter at a Helicopter Convention in New Orleans. It did belong to Clint Eastwood. It was a Bell 206 modified to look like a Bell 222. It had a stub wing attached near the cabin floor housing the main retractable landing gear. The retractable nose wheel went up into the former landing/taxi light space. New lights were on the stub wing. Parker Hannefin supplied the landing gear for this helicopter as well as many experimental fixed wing aircraft of the day.
The paint job was kind of dark but the overall appearance was quite beautiful. I believe it had all leather grey interior. Totally executive.
