Here's my 70's Raleigh Sports that I rebuilt last year. It's not a Triumph, but your bike could easily be upgraded to look similar.

The frame was sand blasted and powder coated a semi-gloss black. I added new decals, a Brooks B17 saddle in honey, matching grips from Nashbar, new rat trap pedals with clips and straps, new cables and housings and a chrome pump. The bars are the original bars, just flipped.
