The OAR should be 1.85:1 I would have thought,the bbc have shown it this way before,shame it is not in it's correct OAR though.:-( I wonder why they are releasing in fullframe though!!
I think you are incorrect stating that Robbery should be 1.85:1. I'm pretty sure, like Michael mentioned before, that the theatrical ratio would've been 1.66:1.
1.85:1 was the US theatrical widescreen standard at the time of the films release, whereas in the UK and Europe it was 1.66:1.
Therefore with this film being a British film it could be safe to assume it was shot either fullframe or composed with the 1.66:1 matting in mind.

"Even though 1.85:1 was rapidly being adopted in North America,
European theatres settled on 1.66:1. The reason for the difference is probably an economic rather than an artistic consideration. The European economy had gone from the devastation of the Great Depression directly into World War II and the effects would last for decades. Installation of giant new screens came much slower in Europe. European motion picture production was slow to get back to its pre-war levels so films composed for wider ratios were not a huge factor and there was an enormous backlog of unseen American films, made in 1.37:1, that were very popular with European audiences. Television had not eroded the audiences at this time either, so there was no need to significantly alter screen shape to differentiate movies from T.V. Over the past 20 years, European standards have evolved to embrace the 1.85:1 aspect ratio as a defacto standard, in addition to the 2.40:1 CinemaScope ratio"
When shown in the USA the image would be cropped to fit the 1.85:1 ratio.
