Help with Backstamp Please

The piece that you show in the link is Wedgwood (no second "e"). It's called "dip" because the color on the outside is only a thin layer. Note that the green of that piece is matte, not glossy. The color is a thin layer of stoneware on top of a heavier base, it is not a glaze as in OP's piece. Glazes are essentially thin layers of glass over a ceramic base. Also note the crispness and clarity of the decoration, much more precise than on OP's piece.

The vast majority of Wedgwood says so on the bottom. It's the rare exception that does not say Wedgwood and virtually impossible that it would say anything other than Wedgwood without adding that name as well.

 

Spot on. Many factories made sprigged ware of course. Much of it moulded in one piece with the body, so it's pseudo sprigged.

 

I'd add that it's only jewellery which has hallmarks.

 

I know it's Wedgewood and it's Matte. This one tried to copy the design even the little grapes in the leafy line.

The one advertised on ebay calls a fake Wedgwood an 'Antique Wedgewood Eturia Olive Green Glaze Jasperware pitcher' and the bidding starts at $70.

Scrolling down that page it says: 'The Eturia pitcher is glazed on the outside, most pieces of Jasperware have the glaze on the inside.'

 

It's still Wedgwood without that second "e". OP's item could be the same age and certainly influenced by the type. My idle guess on the age would be late 19th or early 20th C. Whether a direct imitation or not, I don't know. I think it's fair to say that Wedgwood was the standard for jasperware (which OP's piece is not), but as someone has already said, many companies produced sprigged wares (some jasper, some not), or molded items colored to resemble sprigged wares.

 

Anyone who says jasperware is interior glazed is clueless.

 

I have a similar coffee pot (currently listed on ebay) by Copeland Late Spode. The classical scene is almost identical, but many other details are different, and the base stamp is completely different. It just goes to show that many firms copied each other, despite the registration of designs. The Copeland Spode backstamp on mine includes the Rd number 180288, registered in 1891, and the OP's pot was probably made around that time.
