I am hoping someone out there has access to this... (March 1953) A. Schallamach. Abrasion Pattern on Rubber. Rubber Chemistry and Technology. V. 26 (1). P. 230-241. I know it's a long shot. I tried ILL but was rejected...sad me. Thanks for any assistance. Denise M. Campbell Librarian FBI Library 703-632-3443 [log in to unmask]
