Lot 37A (SNLW) BATTERY POWERED HAND SIGNAL LAMP London Transport 3 Aspect Colour 1st pattern made by SNLW. In the 1960’s BR wanted to phase out the paraffin 3 colour/ 4 colour hand signal lamp. SNLW was asked to make up samples for a trial using batteries as a power source. A sample of Item 13 was submitted, followed by the manufacture of a batch of Item 14. Some were also supplied to London Transport. BR did not take up these patterns instead opting for an aluminium die cast body produced by a manufacturer in Southampton. (13)
