All About Pocket Knives

I picked this up at a flea market , and I cannot seem to find anything about it.
It doesn't seem to be a Little Hunter or a Finn.

Your knife is a post WW2 model 5206 SAB. The 5 prefix on your 206 is the code number for leather handles, the SAB for saber ground blade. Models 206 were available pre-war but my pre-war brochures only show P206 which is a flat ground 4" blade with celluloid handles. They may have made some 5206 SABs pre-war but the brochres end in 1938. Your mark of KA-BAR over Olean, NY and having an aluminum pommel makes it post war but before the mark became KA-BAR over USA.

Gunsil is the THE MAN for KA-BAR!!

Wow , I didn't expect such a thorough response .
Many thanks for your information and expertise .
