Captain Pugwash was Harris Tweed put in period costrtume -and yes, he was in The Eagle too, But not in Dan Dare's adventures.

PC 49. Tin-Tin. Luck of the Legion. Riders of the Range. Tommy Walls even. (Girl wasn't bad either, but you couldn't be seen reading it if you were a boy. Whereas girls could read Eagle, of course. They had all the luck it seemed.)

I'm sorry for anyone growing up with the comics they have these days.
