I must admit, i am not 100% convinced - mainly because they were usually so prolific with their factory marks, but also because the screw/bolt that goes through the top plate and into the pedestal looks a bit crude. All the other compotes/tazzas i have by the factory are moulded in one piece or with the plate cemented onto a pedestal. This has been a marker point; I think i am now confident enough in my knowledge to take a stab at identifying unmarked pieces. It's a very tricky business and one which i'm sure most collectors will face at some point in their collecting careers. When do you start to trust your instincts and all your knowledge gained so far and make a judgment call? It could be that i will get egg on my face with this one. Do take a look and let me know what you think.
one way of checking would be to see if the diamond registration throws up any designs registered for that date. Sadly i don't have any books that would give me info as to who registered it, but i can tell you from checking on the potteries website that it was registered on 15h February 1870. So, it could only be by the Powell & Bishop partnership which ran for only a short period and not a later partnership.
