Did Vacheron sign all their cases?

There is a 1950s watch I am looking at.  The case looks original.  However it is not signed and the only marking on the outside back is the gold hallmark and the numbers "122610".  There is nothing on the inside of the cover.  What do you think, did they use cases like this?

taxes on the import of precious metals (France and the US come to mind) and therefore VC shipped the dial and movement which were cased locally. In such cases (no pun intended!) the case had the agent's or importer's hallmark along with a Maltese cross. Can you post a photo of the inside of the caseback?
