ON THE TOP PORTION OF THE TANK PARTIALLY COVERED BY THE SEAT UNTIL YOU LIFT THE SEAT IS ANOTHER DECAL WHICH IS GOLD IN COLOR WHICH READS "USE ONLY BP ENERGOL, SHELL, CASTROL, VALVOLINE, MOBILOIL, ESSO OR REGENT HAVOLINE." ALSO TO THE RIGHT OF THAT IT READS, "IMPORTANT DRAIN OIL AND REFILL EVERY 1,500 MILES. MADE IN ENGLAND."
THE RIGHT SIDE OF THE FRAME BEHIND THE HEADLIGHT THERE IS ANOTHER DECAL WHICH READS, "MADE IN ENGLAND."
ON THE GAS TANK JUST LEFT OF THE CHROME TANK DIVIDER AND GAS CAP IS A DECAL WHICH READS," WORLD MOTORCYCLE SPEED RECORD HOLDER" WITH WHAT APPEARS TO BE A BIRD IN FLIGHT.
The "bird" is the stylised "Thunderbird", created for the launch of that model in 1949.
It is very similar to the "Speedbird" first created for Imperial Airways in 1932, retained subsequently by BOAC and British Airways until 1984.
According to "Turner's Triumphs" by Jeff Clew, Triumph staff wearing ties with the Thunderbird logo and flying with BOAC or British Airways were often given special treatment by airline staff, who mistook the logo and assumed they were also BOAC/BA staff.

THE NUMEROUS PICTURES ON LINE THAT I HAVE SEEN, INCLUDING THE ONE ON MY HAYNES SHOP MANUAL DO NOT SHOW THE BIKE WITH TURN SIGNALS.
All 71 and later Triumphs and BSA's - with the exception of competition versions like the BSA B50MX - were fitted with turn signals as standard.

Haynes manuals are infamously unreliable.
MY HANDLEBAR CONTROLS, I WAS TOLD, ARE THE "AMAL TYPE" THEREFORE I HAVE NO TURN SIGNAL SWITCHES NOR MIRROR MOUNTING HOLES. (SPARX TYPE).
73 T100 Triumph parts book .pdf pages 62 and 63 captioned "HANDLEBAR AND CONTROL LEVERS":-
. The only parts made by Amal were the TWISTGRIP assembly (part #3) and AIR CONTROL LEVER assembly (part #14).
. The original switch clusters were made by Lucas, the bodies were lacquered aluminium alloy castings ("LUCAS" and "169SA" cast into them), the pushbuttons and levers were black plastic, illustrated and functions listed on .pdf page 6 of the 1973 Triumph 500 Owner's Handbook
. Each matching lever perch casting was also lacquered aluminium alloy, included a 5/16" i.d. hole for mirror mounting (these holes had been included in all 70 and later lever perches).
These switch clusters and lever perches were fitted to all drum brake Triumphs and BSA's between 71 and 74. However, 73 and 74, the Daytona was the only model still using the same right hand switch cluster and lever perch, because it was one of only two models that still used a front drum brake, lamp switch incorporated in the brake cable (the other drum braked model was the TR5T, had different handlebar switches, the other models had a front disc brake from 73, lamp switch incorporated in the similar right hand switch cluster).
Levers were originally polished alloy also but, possibly by 73, they had been changed to chromed steel (still pivoting in the alloy perch castings).
If your bike does not have the handlebar controls illustrated and listed in the 73 parts book and Owner's Handbook, it does not have standard 73 handlebar controls.
Sparx is a supplier of pattern copies of original Lucas handlebar switch clusters. Their copies are identified by "SPARX" cast on or stamped into bodies where original Lucas had "LUCAS" cast or stamped.
