Brilliant C-flat..many thanks! Chung..of course!

That site also reminded me about Mytek the Mighty!

Actually I'd forgotten all about Valiant (which is where I read him in those early sixties) and thought he might have been in The New Hotspur or the Victor, which were my other reading of choice at that age! Thanks again.
Now, any takers for those pesky Inca with their sunrays??
