I have got an oil vinegar set shown below.
There are marks as depicted in the photo.
On the frame, there is only an Odiot mark (the first to the left) but not the Minerva mark.
On the stoppers, there are both Minerva (in the midde) and maker's marks (to the right).
I have learnt that the the latter most probably belongs to Francois Julien Doyen active 1852-1870 in Paris. I have learnt also that the Odiot mark is either from the 19th century or quite new as they started to use it again in the fifties of the last century. Although bottles and stoppers fit reasonably well I am not at all sure they are an original set. Last thing I learnt: Odiot (sometimes?) did not put the Minerva mark on items meant for export.
I wonder if the cruet frame is made of silver (it definitely looks like), and when it was made: in the 19th century or much later.
Any help will be much appreciated.
Kind regards,
Georg
