Check Opp. 34 as a possible dupe

It looks like we've got a problem with MS. Oppenheim 34, which looks to be a dupe of MS. Oppenheim 333. I'm guessing a file got erroneously copied over, especially given the [DB object](https://digital.bodleian.ox.ac.uk/objects/4a83e8ab-6ca2-45c2-b24d-7a53736a5d13/). Can you investigate and see what's happened?
