My grandad owned a Triumph t90 in the late sixtys to about mid to late 70s and is trying to buy it back. Its a 1966 Triumph t90 reg GDF 40D. If anyone has any details on the bike or knows the owner can you please reply to this post. Thanks.
The DVLA has a service which can provide information on a bike if you can prove a genuine connection to it. I used it once to track down previous owners of one of my bikes which had incorrectly been categorised as a Cat B. I seem to remember information about the service is well hidden on the DVLA site but maybe worth searching for. There are severeral Triumph forums so well worth posting in the relevant vintage/classic section of as many as possible.
