New purchase: Chatwood safe

[safeman]

Congratulations on your new acquisition.

I'm out of my comfort zone on the matter of Chatwood locks but no doubt someone
will come to your aid.

In case you are impatient, here's a little piece on the lock.

Your Chatwood Lock.
The first lock Patent was dated 28^th May 1860 and was probably made for Chatwood by the
the famous locksmith Charles St Aubin to a design by one of Chatwood’s partners at the time,
Robert Wharton Parkin. The levers incorporated the spring which was a new concept and the
key operated in the centre of the lever pack which was also new and was designed to prevent
the insertion of gunpowder of any effective quantity.
It also incorporated an anti-pressure bolt stump to prevent picking. This lock also had the facility,
if required, to be key-retaining. i.e. the key could only be removed if the boltwork was thrown.
(to preclude leaving the key in the door through forgetfulness).
