I wonder if anyone can help me identify a mark on a watch case and the significance of a number that appears on the inner cover? The watch is from 1870/1, does not work, but is still a beautiful object, even if, I think, of very little commercial value. The mark in question is a circle containing a cross with curved ends and triangles in between the extremities of the cross. The number on the inner cover is 8614. All the other marks (lion, leopard and date letter) appear to be standard for 1870/1.
I have been trying to upload a photo of the watch and a drawing I have done of the peculiar mark, but, so far, with no luck - I am not terribly good with computers - so any help on this would also be appreciated.
UPDATE. I have just spent two hours researching different methods of inserting images, and hope that I have now uploaded my drawing! I hope it has worked.
