C JUL HERBERTZ 21cm 1960s Italian Trapdoor OTF switchblade knife flawed

Vintage 1960s C Jul Herbertz 21cm Italian trapdoor switchblade knife measures 21.2cm (8.25 inches) open and 4.5 inches closed with chrome plated brass bolsters, nickel silver button and safety cap. Most likely made by Rosa Uliana Primo in Italy. The knife has a couple of minor issues and is priced accordingly. The flat swedge grind blade is 100% full with original finish and some light scratches and it stamped C JUL HERBERTZ over IMPORT on the ricasso and the backside is stamped PATENT ROSTFREI. The genuine horn scales with red dot safety are black and the front is in good condition, but the back scale has a crack through one pin and is scuffed some. The knife functions great with the blade opening fully when the button is pressed. Press the button again to release the blade from locked open position to be closed and cocked into firing position with the hinged trapdoor. Safety works. G+ condition.
