Thorn Riga Lantern Installations
The Thorn Riga is the successor to the Thorn Beta 79 and Beta 99, following years of design improvements and testing. Competition from the wildly popular Thorn Civic 1 and WRTL 2600 kept the numbers of this lantern down (especially in the midlands) although some areas of the UK did still use it in larger numbers.
