Help identifying: G.P. Co Mark, Makers Name and Pattern.......See Pics

[biznis_3]

Hello,

I have been trying off and on for several years now to no avail .......to correctly identify this Mark: G.P Co and the name of the Pattern, if any....... that is on these dishes.

Through my research the best I have come up with Glamorgan Pottery(Baker, Bevin & Irwin) and Grange Pottery........both are just guesses......and I have nothing definitive to support that either was the maker.

These dishes were handed down from my Grandmother who is now 98 yrs old and they were handed down to her as well.

I am estimating the age to be mid to late 1800's........early 1900's possibly, but not likely.

The dishes are very heavy as well if that helps at all in identifying.

As far as the pattern I was thinking Flow Blue, but that doesn't seem likely either.

I don't mind doing the research but trying to identify these dishes have just left me stumped and frustrated.

The only mark on the back of the dishes is G.P. Co.

Any help or even a point in the right direction anyone can provide would be most appreciated.

Thank You Very Much

Tom V.
