GT6 Mk1 Reverse Lamps

["Alecks & John Graves" <alecks@globalnet.co.uk>]

Hi All,

   I was at a Triumph meet here in the UK this past weekend
and came across a couple of GT6 Mk1's that had different 
rear lamp set-ups. One had only stop lamps & turn indicators
while the other was like mine which has these plus two clear 
lens reverse lamps. All 3 are Mk1's built before Sept. 1967.
Does anyone know what the cars should have. Any help will 
be appreciated. TIA.
Cheers,
John Graves
