Vacuum Tube types have changed over the years. The very oldest tubes looked more like light bulbs and had a screw type base. Most 1920s tubes had glass envelopes and large bakelite bases with four or five pins. Tubes from the 1930s and 1940s typically had glass or metal envelopes and six, seven, or eight pins. A Locking metal base was used on tubes in the late 1940s, they were called "loktal. They were superseded in the 1950s by all-glass "miniature" tubes with very thin pins. Keep in mind that different tube types overlapped. For example, some radios continued to use loktal or older tube types into the 1950s. However, if your radio uses glass miniature tubes, you know it must have been made after the end of World War II, and was likely made in the 1950s or later.
