Looking to try and identify the approximate age of this old Chubb 2 door Safe.

[bobneiht]

Firstly there is no serial number to be located on any of the locking pins or anywhere else on the safe.
Secondly there is also no weight impressions to be found on the top of either of the doors or anywhere else.
Don't worry we have looked long and hard for them.

Without removing the lock completely (riveted in) there are no serial numbers on it to be seen either.

Front doors are half inch thick steel.
Size is 48" high x 36 " wide x 36" deep with 2 lockable draws.
The green paint seems to be the original colour, just oxidised and faded.

This by all accounts from my research on this forum is an early Chubb Fireproof Safe made between 1839 and 1866 at 57 St Pauls Churchyard, London at per the 2 front plaques.

We can find no evidence of tampering since original.
Have attached pictures for viewing.
Any help is greatly appreciated.
