yes I can now see the W below the crown, for either William 111-1V, the M is probably a Makers or Traders mark.I can make out,
Dagger- stamped in London.
ewer - is the London mark used to validate weights and used between 1590 and 1826.
If that was a "W" I would say William 3 but it looks like a "M" so i dont know.
The other is a crown probably with a letter under it witch would tell the king/queen.
