Does anyone in the group know this hallmark? The R is backwards and it’s stamped 6 times on the base and handle of a cruet set. The sterling on the glass bottles are all marked for Charles Thomas Fox, English 1840. The set seems to be a marriage with the bottles and not original.
Interestingly the whole mark is backwards - I have not seen this before and have no explanation for how this came about. In addition the large R is normally RD (D written as a superscript); I think that I may have seen this variation but I can’t be sure.
It is a British design registration mark (see British Registry Date Numbers - at 925-1000.com). Here we see that the design was registered on 10 January 1871 so it cannot have been made before then.
Logic dictates the rule in Occam’s Razor applies. Which would indicate that the photo you have is reversed or a mirror images. It have become such a common problem in the world of selfies that an ap exists to correct it.
