John, after I wrecked my ’72 T100R, I fitted a Trident front end with disk brakes. I had to have different bearing races fabricated to adapt it to the frame, but it worked out. So, there’s at least one T100R out there with disk brakes, which I suppose could be mistaken for a T100D, so I would advise anyone lucky enough to purchase a T100D to verify the serial numbers first. (I’d actually like to have the bike back, but I have no idea where it is or who owns it).

I own one of the few Daytona T100D’s from 1974. The front end (forks, wheel, brake, mudguard and clocks etc) is as on the T150V Trident. Silencers should be the long cigar shaped items as on the T150V and T140V. There are also quite a few engine modifications to improve oil feed and reliability but not so much performance.
I believe the ‘D’ suffix indicates ‘development’ and not ‘disc’ as is widely thought. Production numbers vary from 10 – 14 depending on which book you read.

Yep! T100D one of only 10 produced if it’s genuine. TMS at Nottingham have two I believe.silencers have been changed to the earlier style, they should have been the tapered Dunstal style silencer.

There was also a small batch of drum braked Daytonas on the line during the sit in, these were completed and sold through the midlands dealer network. They all have the same rear light as the bike in the photograph.

I believe this is a prototype 1975 Daytona. Note the disc brake and later style front fender. It’s certainly 70s with the directional lights. The silencers are the early style, not the larger ones used on the later US Daytonas.
