Also, confirmation of the maker's mark please, possibly Nathaniel Locke
Thanks in advance

Contrary to this, I believe the mark comparison above shows the mark used by Nathaniel Lock in 1713 had sufficient space between the key and the letters that it is OK for the key not to be seen on your piece....the key in his mark is too close to the LO not to be seen on your mark and the symbol below the letters is not as much like a cross as in your picture...
