OK . . . . First, it sounds like this Bomford fellow is just saying it looks like his BC, but is not providing positive confirmation that it is genuine, that it matches one he has seen. Second, who is to say he isn’t in on the hoax? If someone were to create a bogus Australian BC, they would not want it to be for a person who would debunk it.
The guy’s saying it had his address on it, but what address?
