i have some 75 pieces with the JPT identity mark and am looking for any additional information and photos i can find. i believe they produced something less than 500 pieces. It was located near JW Remy and there was a tie in between the two companies other than through marriage.They shared a firing kiln and more although we don’t understand the “more”. It closed around 1930.
Paul, the copy I have is extremely poor quality. You could check them out on the SCI catalogs section. If you still want a copy I will have to see if I can copy it without losing too much of the limited detail.
