A beautiful teapot though unusual for the period--some have speculated that the spout was a later replacement, but metal analysis suggests it is probably original. The coat of arms are a slightly later replacement, as faint traces of an earlier engraving can be seen. The extant arms likely belonged to a north Welsh family, possibly Edwards or Trevor.
I love teapots like these enough that I acquired one, a Charles Harleux 950 silver teapot.
That curved black wood handle does seem to be quite the popular style back then!
Not a fan of the straight spout with all the curves on the rest of the pot - it seems jarring, and I can see why people thought it might have been added later.
Awesome! Yeah I hear you about the spout, I like the more typical short, curved type. But I also appreciate the iconoclasm of this one.
