BONSA SOLINGEN D.B.G.M ROSTFREI 23cm German OTF BLACK Automatic Trapdoor knife

Rare Vintage BONSA SOLINGEN D.B.G.M ROSTFREI 23cm German OTF BLACK Automatic Trapdoor knife made in Germany 1970s or 1980s. It measures 23.3cm (9 3/16 inches) open and 5.25 inches closed with Black synthetic coated non magnetic steel frame with steel trapdoor, button and safety. The flat grind spearpoint blade is 100% full with the original factory finish and some light scratches and nice deep stamp near middle of the blade that says BONSA SOLINGEN GERMANY and the tang is stamped D.R.G.M. The black synthetic covering is in very nice condition, but it does have the typical shrinkage near the sliding safety as you can see in the knife side pics. The knife works well with the blade tip inside the knife when closed, opens fully and locks up well. Blade flies out to full open when the button is pressed and falls back when button is pressed to close. You reset the blade for firing with the trapdoor by pushing down on the trapdoor. Safety works. EX+ condition.
