| Description |
When the British VT-32 was equipped with the American four-pin base and vertical element assembly and another glass, it was used by the US Navy in the World War I under the designation SE-1444. Some of the SE-1444 tubes have clear glass, others are reddish in color, which may be the cause of a phosphorus getter or an magnesium getter. The base on the earlier tubes was made by the Shaw Insulator Company, who were associated with Moorhead Laboratories. Late versions of this tube had porcelain insulation in the base.
