English silver salver with inscription

Thanks for all your help.

It’s pretty unlikely that the salver dates from earlier than 1730. The missing mark is, of course, the maker’s mark which would have been interesting to know. Can you post a picture of the dedication engraving? The significance of 1511 might become a little clearer. Can you also go back and edit your initial post to make the images appear (you need a double / after http; i.e. http://).

Thanks for all your help.
