This is made by Hollinshead and Kirkham, originally of Burslem in Staffordshire. They moved their works to Tunstall in 1890. They produced china/pottery mainly for the middle of the market. After the WWar they started making art deco style dinnerwares to boost slumping sales which have become very collectible.
This handle does make this more unique...thus more desirable to collectors of H&K
