Stratford SE 73012 will be a size 3520 made in 1972 and weigh about 970 kg.
The Ratner will be a size 5020 and if the code on the bolt end is SUR it will be an Executive, and if STR it will be a Trustee.

The weights will be very similar at around 1600 kgs.

The Cash Ratings will be approximately £4000 for the Sterling, £8000 for the Executive and £10000 for the Trustee but my personal belief is that these Ratner figures are unrealistically high.

The Chubb safe has a code stamped in the middle bolt but I cannot make it out and in any case I don't have the codings before 1964.
