The first pic is an original from 1834 art work by Catlin - Comanche made - note not a lot of beadwork on early ones. The real heavily beaded ones so often seen are post 1870's and later reservation period .
This is an original circa 1850-60's
Shoulder straps show up on cases in the A.J. Miller prints from 1837
