Grainger made Bute and Hamilton flute shaped cups from the early 1800s. Most of these have a large round ring handle set quite close to the rim. There are two types of ring handle: Type 1 ring handles are round in section and are typical of Grainger; Type 2 ring handles  are more flattened in section and are very similar to those made by Chamberlain. In Chamberlain cups the triangle under the ring has a shorter side next to the ring while in Grainger cups the two sides formed by the handle are nearly equal. Grainger also made Bute cups with loop handles with an inner spur   (click to see whole Grainger New Oval teaset)
