Dating certificates provided some interesting information and can
give details such as the date the bike left the factory and the
original dealer they were shipped to.
They can also be very important if you are in the UK and have a
Tiger Cub that is not on the DVLA
computer. Before DVLA will register (or re-register) a vehicle they
require documentary evidence of the vehicle's provenance. A dating
certificate is usually required for this.
The late Mike Estall used to maintain an official Tiger Cub Register
and provided dating certificates for all Tiger Cubs with valid frame
numbers. His Consolidated Parts List & Index gave useful sizes
and references not covered in the official Parts Books.
Since the sad passing of Mike in 2017, the Triumph
Owners' Motor Cycle Club now offers a similar service.
