This helmet is part of a collection that we purchased a few years back from the family of a former Marietta employee.  The employee would occasionally bring helmets home that were going to be discarded, for his two sons.  His sons soon had a very nice collection of NFL helmets with just about every team offered in the early to mid 1970's.  This helmet is a game worn original Marietta Kineomatic 21 Leather Padded Minnesota Vikings helmet from 1973.  The helmet is original and has all of its very rare Marietta leather interior padding.  It comes complete with the original leather jawpads and original 1970s Schutt NOP facemask.  The helmet is in excellent original condition with no modifications.  The original clips were broken when we obtained the helmet, and reproduction replacement clips are now in place securing the original facemask to the helmet.  The original hardware is used to secure the facemask clips to the helmet.  There are no player identifiers on or inside of the helmet.  Original Marietta factory decals are inside of the helmet with the 1973 datecode.  The helmet size is 7 - 7 1/8.  A great rare vintage Marietta helmet that is very hard to find.  The helmet was sourced to us as you see it in the photos from a former employee of Marietta.   If you know how rare Vikings helmets are - together with how rare Marietta NFL helmets are, you know what this is.  You'll never see another one.
