Fire Damages Reliant Paint Shop ( Tamworth Herald: Friday November 19 1965)

Production is not affected by a fire which damaged a paint shop at the Reliant Motor Company Two Gates works late on Tuesday night.  Four workmen in the shop escaped without injury but two cars were burned out, spraying equipment and paint supplies were destroyed and the roof of the 50ft by 15ft building were severely damaged. Brigades from Tamworth, Lichfield and Burton-on-Trent were called to the fire which was brought under control in thirty minutes. Firemen prevented the blaze from spreading to the main assembly plant. A spokesman for the firm said that production would not be affected by the fire. The cause of the fire is believed to have been a fault in the extractor unit.
