Brok Windsor is a great-looking strip. It turns out that this was reprinted in a 194-page collection by Bedside Press (in black & white, just like the original comics). I'm going to order the book, based on what I saw of Brok in BETTER Comics here. http://bedsidepress.com/product/brok-windsor/
There's also a review of the Bedside Brok Windsor book and an interview with Stables' son (also named Jon) here: https://www.comicbookdaily.com/collecting-community/whites-tsunami-weca-splashes/brock-windsor-1944-1946/
