The major problem at the end of the day though, is you would spend at least two to three times what the finished machine fetch on the market. For example, it is reputed that certain collector bought a Wirraway recently at significantly less than half what it cost to rebuild back in the 90’s, and it was a very good, very complete project to begin with.
Recovering, restoring, owning, displaying and flying warbirds. Is NOT a profitable venture. Yes, very large numbers are involved, but that is NOT profit. If the Mark I Harvard floats your boat, and your using your own money. By all means go ahead and enjoy yourself. You are doing the world a favour and a very small percentage of the people on the planet will be grateful to you. And, yes, some idiots will critisize you. “Such is life”.
