All About Pocket Knives

Ran across this little fixed blade knife stamped PALMAR.L.A. JAPAN on the tang. It is 6 1/4" overall with 3 1/4" blade length. Scales are bone. Has anyone seen anything like this before? I'm not familiar with the manufacturer and am interested in age and background.

Could the name possibly be PALMAX? I've seen that name before.The knife was likely made in the 1950's or 60's and came with a small sheath.Some of them had a compass inset into one scale.Value is minimal.
