Found in an estate liquidation on Madeira Island Portugal, from a mid 19th Century Portuguese homestead.
Vintage Souvenir / Premium pocketknife in the form of a rifle.
Made in Portugal, marked "Sica Inox", closed it measures 2 3/4 inches long opening to measure 4 3/4s Inches.
The handle is a polished butterscotch colored plastic and is engraved "Souvenir of Madeira".
I have inserted a standard size playing card in one photo as a reference for size.
The condition is quite good, no breaks, bends or scratches, the blade tip not dinged.
This is a small knife that is really quite unique.
MUCH OBLIGED
