I am really confused about the material of which the sabot was made. Some authors state formed/pressed papier-mache, some state coiled paper. I see the rings on your photo (not very well), but they could be from the process of cutting/facing the bottom of the sabot. What say you - really coiled paper? Guy and Leonard, extremely knowledgeable on the subject say coiled paper that "unfurls" in shooting. But the contemporary accounts state that the sabots didn't disintegrate/unfurl and could hurt the troops nearby if hit. Hence my confusion...The base of the sabot showing the rings left from winding the sabot
Disagree. There were even shells with sabots of papier-mache for muzzle loading rifled cannons. I need to check with the book on exactly what model, don't remember right now.papier mache is impossible, it would never stand the stresses.
