Triumph Pin [Series V-VII] [Unconfirmed]

I am just about satisfied (nay, triumphant) that I have successfully tracked this one down, but am still not 100%, hence the 'Unconfirmed' tag. Until I can find more conclusive evidence either way, what tips it over the edge for me is the slightest hint of the lower curve beneath the logo text, and also the gnats' wing of silver trim bordering the circumference of the pin itself.

Quarantine, Series V

Now the largest UK motorcycle manufacturer, Triumph originated in Coventry, though the modern iteration of the company operates out of Hinkley. This pin can (probably) be found on the screen-right lapel of Lister's leather coat. So far, I have caught a glimpse or two during Quarantine and Epideme, but as yet, not Terrorform - the only* three episodes during which the coat appears. That said, it does seem to have survived the perils of wardrobe storage/space adventures for at least five years, unlike a fair few of its badgeular fellows.

This is the best quality example I have found thus far, despite costing more than a few penny-cents. Should anybody ask, its well-worn pits and scuffs are, I dunno, asteroid damage. Made in England, with one of those common-or-garden over/under, V-swivel, subcutaneous-capable clasp fittings on the reverse side. Clear?

Measures approximately 35mm across.

*Not counting the few stray pixels seen during the brief recap that opens Nanarchy, or the opening title sequences to all six episodes of Series V
