I first read about the Campbells and the Bluebirds as a schoolboy. I was pleased and surprised to read that the Bluebird in which Donald was killed is being rebuilt. There's a premium article in the DT here:

A couple of snippets from the article which I found interesting:
This thing wasn’t built very straight,” he says, fiddling for a tool on a cluttered workbench. “The bow is half an inch out of line with the stern. The design was good, but the execution was shabby. It leaked like a sieve.
That design was the vision of innovative engineers the Norris Brothers, but construction was handed to Salmesbury Engineering, near Preston, which, ordinarily, made buses. “Bluebird was built to the standards of a bus,” says Bill. “It’s strong and solid, but crude”.
