Old Guard Helmet Liner, Boots + 1950-1954

[amberg1853]

Had these items for a little while, interesting but they are a little outside my collecting area and trying to narrow things down.  These belonged to Warren S. he served from 1950-1954 and was a member of the 3rd Regiment Old Guard and was among other things detailed to guard the Tomb of the Unknown Soldier. Liner is a CAPAC with the original leather visor strap.  Flag is 50 star and might have been his funeral flag.  Leggings are dated 1948.  Any ideas on a ball park figure for the group? I don't have the photograph in the group, his daughter wanted to retain it but that is him in his uniform and shortly before he passed away in 2015. Boots have been died black on the lower third. Thanks in advance, Brian
