The lid unpictured has W S stamped into the medal near the center on the underside. The brown numbers are 1006 with a T under it, The mark is crowned top with W & R inside just under the crown, also inside the mark bottom of ring it states STONE-ON-TRENT. Looks like a bird in the center of the mark.
Below the mark it states POPPY RD NO 157 (10?) On this part the D in RD is raised and half the size of the R with a underscore and the O in NO is the same half sized with an underscore.

The marking on the rim is very, very hard to read. It looks like there is like a shield with a crown and I think 2 letters under the crown inside the shield, the shield is laying on it's side at the end of the lettering. It looks like 4 letters the only one I can read is the 4th it is definately an S. the 4 letters appear to be in old English style lettering.
