No makers marks to the bottom, so unsure of the manufacturer.
I beleive this teapot was used only for display, I have taken a few pictures inside to illustrate.
Combined postage can be arranged please message if you spot something
else in my shop (if the combined weight remains below 1kg including
packaging) postage will remain the same as for 1 item, if not the rough
postage cost will be around £5.
