Base same as the UV199, but "Isolantite" (a type of ceramic). It was sold in a metal can. This tube was first made during 1925 but discontinued later in the same year. It was reintroduced late in 1927.
This tube has a bigger bulb than the UV199 and the elements are mounted horizontally to the base.
