Already found on the net most of his works, besides "Great game" (1942, 1981), "Leader. Handbook for managers of the Zawisza branches" (cz. 1–2, December 1942, II 1943, III 1944) and "Information Bulletin"

Would appreciate very much any help finding downloadable facsimiles of the war time editions.
Thank you!
