I owned an authentic one in the 1960s. My dad gave it to me, They have wood on them and they were better made in the 30s or 40s but mine was still good. Mine had a stainless steel blade. The middle one in the picture I believe is the oldest and the one on the left is newer I believe. The one on the right if it hawood on it, compare blades and I'm bettin they're all real Barlow knives ! Hope that helped !
