TR4A chassis colour

[don spence <dspence@oanet.com>]

Triumph prepared "demo" cars that had all sorts of "options" on them 
for loan to magazines (for review) and photo ops as well as for display 
in motor shows etc. Most likely the car used in the brochure photos was 
specially prepared for this use. In Production, colour coordinated 
frames would have been a logistical extravagance.

I've had 5 TR4As and all had black frames.
