The 1817 and 1818-1819 marks look very similar, both being the initials ACC with an imperially crowned cup, and to my eye the mark on your piece looks more like the later mark. Also, Arminjon does not give a cancellation date for the 1817 mark, so it is entirely possible that it was still used after that, with the 1818-1819 mark being a second mark, perhaps larger or smaller for different sized work. So either way, I don't think the mark is problematic.
The same cannot be said of Aimée Catherine Clérin, the widow Lecour. Even though her mark was registered in 1807, she does not appear in the Paris trade directories until 1813. Moreover, her husband - Antoine Lecour - does not appear before that as a silversmith at all, nor does Arminjon give a mark for him.
However, their son (and Clerin's successor) François-Marie Lecour is listed as a silversmith at 32 rue St. Jacques le Boucherie on his 5 Dec 1807 marriage record to Anne Charbonnet. He was 26 at the time, so one would assume he had learned the trade from his father and that he was the head craftsman at his mother's shop. The only plausible scenario I can think of is that Antoine Lecour was working outside of Paris and that after his death his widow and son moved his workshop into the city.
Clérin is listed in the Paris Directory as Madame Lecour at 11 place Thionville/Dauphine (the street reverted to its original name in 1814) from 1813 to at least 1829, and her son as Lecour fils in 1833. His registered two marks - one in 1830 and one in 1832 - at the same address (the first mark at 14 place Dauphine, certainly an error) and both were cancelled on 31 Mar 1834. He does not appear in the Paris directory as a silversmith after that, evidently taking up another trade, as he did not die until 23 Jan 1859.
So given all this, I think that the dating of the piece to 1817-1819 is a little restrictive; I think it more likely dates between 1819, when the "old man/vieillard" mark was introduced, and 1830, when Clérin was succeeded by her son, Lecour fils.
Hope this helps!
