As far as I can tell by comparing this to the last Cook I had, it is a duplicate in every aspect with the exception of being a no name so I will go out on a limb and say it is a more than likely a cook porcelain. It is a bright Canary yellow and is VVNM cond. Inner skirt is extended 1/2" and entire pinhole is glazed which is kind of unusual for most porcelain. Great colour piece! $15 + $5 shipping in USA.
