Welcome to the Forum.
These look look like typical Martin, Hall & Co. wares, a milk jug and sugar bowl, made for the catering industry, they are what are usually described as hard-soldered hotel ware. It's known for its hard-wearing durability.
The marks are what you would expect to find, with the exception of the 'fouled anchor' mark, this would likely have been struck for the benefit of the customer (probably a shipping line) so that they could identify their own property.
I would say the items date to around the 1920's-1930's period.
