Antique Flow Blue Tea Pot outlet from 1800's

This antique lg tea pot is an ironstone ware in flow blue pattern. Circa 1845 made in Montreal, Canada
measures 6 3/4 H x9 W on the bottom stamped Montreal Glennon
There is a bit of crazing but not much for its age, one small line on the side. Ilooked for information and the only thing i found was he may have been associated with John Alcock making pottery in Canada. The problem is no lid.
It is a beautiful piece just the same.
I put flowers in the pot and love it! The blue and white is so bright, i love outlet it as a vase.
