Help ID - Warranted, Unicorn, Lion pottery mark on teapot

by Alice
(Hastings, NE. USA)

The only identifying mark is a shield with "warranted" printed above a crest. The oval in the center of the crest is blank, and the figures on the sides of the crest are a unicorn on the right, and a lion or monkey on the left with a crown. At the bottom of the crest are four small feet which resemble the number 8.

The top is lined with gold, as is the bowl as it goes from bulbous round to round and into the lip of the pot. The gold on the handle is leaf shaped.

Thank you in advance for any assistance you can offer.
