Hi Nick
I'm pretty new on here myself but have been collecting pressed glass for a lot of years so I'll have a go at this.
Used to see this pattern around quite a lot, but I think this is the first one I have seen with a lid. As Frank said the concentric circles on the base are part of the mould, not particularly press/plunger marks, they would have shown up better when the piece was pressed in clear glass. These 'rings' are seen on pieces of Davidsons pearline, and they are also present on the 'bugle' vase (Slack page 84, Hajdamach page 349) which is attributed to Davidson. So I would say Davidson circa 1890.
