As my username would suggest, I love DeHavilland Beavers. This one is in INCREDIBLE shape. Do you know who did the restoration work? I'd want to say Kenmore, in Seattle WA. but I couldn't tell you for sure. $540,000 is a VERY reasonable price for this airplane by looking at the condition it is in, it makes me wonder about the engine, it could possibly have high hours, that might be why they are asking a relatively low price.
Again, a beautiful picture, and beautiful aircraft!
If anyone here hasn't ever flown in a Beaver, I STRONGLY suggest you put it on your "to-do" list!!!
