Right, off the top of my head, I've got:
An Autoplas rear window louvre,
A Formuling bootlid ducktail spoiler,
A Group One front spoiler,
A Formuling steering wheel,
An assorted collection of Instrument Nacelles,
A Unipart bespoke to the Dolomite/Toledo stainless steel and walnut roof rack,
A Unipart bespoke to the Dolomite/Toledo stainless steel boot rack,
Unipart Dolomite mudflaps,
A Leyland ST Dolomite stripe kit,
A Leyland ST sunstrip,
Assorted period alloy wheels, 15 sets or so in total,
Assorted Mota-Lita steering wheels, one in ST wrapping,
Some Leyland ST anti-roll and tie bars,
Assorted Blaupunkt, Radiomobile and Motorola radios, some with original fitting kits,
A Karobes side window deflector,
A pair of Karobes headrestraints,
A set of Karobes seat covers,
A pair of Leyland ST harnesses,
Assorted Kienzle and Smiths gauges,
Various go faster bits like an LSD etc,
A Unipart immobiliser,
A Sparkrite alarm system,
Pirahna electronic ignition,
Various Kenlowes,
A Mocal oil cooler,
A Smiths Mini-Tac and about 10 other tachometers (a bit of a fetish those!),
An Astrali 'upgrade pack' with steering wheel, gear knob etc,
A Toledo TS stripe kit (I had these re-made),
A pair of Lucas Square '8's,

...and lots and lots more. Ahem.

Essentially I've been collecting NOS parts for my ultimate Triumph for years, but sadly don't have the time any more so will be selling most of the above. I'll keep some things, some bits have 'dibs' from other enthusiasts, but there are nine boxes still to open and a shed to clear! Then I'll get round to the all the standard spares etc.
