I was told this is an Italian collar badge for the infantry assault engineers, introduced with circular order dated December 24, 1941, n. 21. I have not seen another like it and am interested in finding out more information, as well as it's approximate value. I seems quite rare. It is part of a collection I acquired 25 years ago. It appears to be the correct size and looks genuine. Any information or thoughts would be appreciated. Thanks. Italian Collar BadgeItalian Collar BadgeItalian Collar Badge
