probably Stelton
Hi there, you seem to have a pre-sixties Stelton teaset; quality of items as well as the linear design accentuated with the rosewood handles point in that direction and Stelton only started marking their items with the firm´s logo after 1961. Congratulations to an early designer set worth about $ 300 in the US, not sure about Europe though.
