Blimey Brock I've gained a whole new respect for you!!
Now can I get you to go and put me in your Will for those? Please?
I can't recall how many I've read, but I know there were 104. I vaguely remember borrowing one of the frontispages decades before photocopiers, so I could keep track of my reading.
For the record, I was dubbed "Biggles" while teaching out in Bourke. Apparently I evinced a greater appreciation for flying than teaching. I'd beg borrow or hire any locally hangared lightie I could get my hands on. Being a relatively remote town, there were plenty of opportunities to rack up the hours.
Almost every time I try to use it as a pseudonym on the internet it's already taken, and I'm offered "Biggles 18" or somesuch. So there are a lot of wannabes out there!
