Mason's antique vintage white blue Manchu made in England ironstone vase

Made between 1920 and 1923 as evidenced by the transfer print angular crown and absence of "Made in" before England which was added in the year 1923. Stamped "Mason's Patent Ironstone". Factory mark appears to be "08" in red. Green serial number is no longer legible. Very good condition, there are two chips to upper rim and there are flecks of what is probably decades-old dirt on inside bottom. This should come off easily with a cleaning but unfortunately my dish brush couldn't fit inside. Crazing lines are present on inner and outer. Very beautiful piece!
