Very rare original Chatwood Invincible patent double bitted safe lock. Amazing unspoilt condition with all working parts/springs intact. Has the anti-pressure device with floating talon. 4 original hand made cheese head bolts securing the cap. All the lever gates appear original and not filed out as with many other safe locks. Powder proof steel case with anti-drill inserts and key way. Weighs over 2kg I cannot see any repairs whatsoever. Would make a lovely centrepiece to any collection. Would clean up nicely having so many brass parts. No key. Serial coded.
