After I wire brushed it, I can read W (something) and part of the G and just below that ENG, It doesn't seem to include PATENT between the words Wright and England like most of the photos I have seen. There is also a number 6 stamped into the front left foot. As far as I can tell I can't find any of the stoneweight markings.

Can anyone give me an idea as to what this is and what I should pay for it? As far as repairs go, what should I do if anything? Thanks for the input.
