Tab books

I know this is a very long shot…Just wondered if anyone knows of anywhere I could lay my hands on the Roger Brown “Stealin’” and “Blue Skies Black Heroes” tab books. I’ve tried Leola and all the online booksellers/auction sites I can think of. Leola ignored my question/email and they never ever seem to come up anywhere! I used to own both and they were mislaid a couple of years ago. I’ve been searching ever since but no luck!!
Thank you all in advance for anything you may be able to suggest.
Also thank you for all the entertainment and info that all you wonderful people give...I often lurk here but don’t usually post so please forgive me.
