I have this what seems to be a very early-maybe a prototype of this Frankoma casserole. While the bottom is not marked ‘Frankoma ‘ it is marked with the ‘5P’ mold. It looks very rough as if it were not kilned correctly. Any thoughts?
The 5P is in this list of mold numbers !! Its possible yours was sold as a :”second” !! Not sure about Frankoma but other potteries sold the “not perfect” pieces this way !!
