R.L.& SON LONDON Help

[Hoosier49er]

Can anyone help me ID this one? The seams dissapear at the shoulders, crude lip, and there is nothing on the bottom but "pitting" where it looks like it was set down on sand or something while it cooled. I'm looking for dates, value, what it contained, etc.
Thanks in advance!
Joe
