It is vintage from about the 1950s and made by a company called Bliss Brothers. It is marked as sterling silver (925 stamp). It has some signs of wear (overall patina) but it makes it authentic and very vintage looking. Overall for the age, it's in excellent condition.
The model shots are to give an idea of the feel of these. The ones on the model are also in the shop. You will receive the yellow oval one in the first few photos.
