"S.H.I.E.L.D" Agent Phil Coulson's Neck Tie

Does anybody know the style/manufacturer of the necktie Clark Gregg wears in "The Avengers" ??

It's been a few years, and I don't know how interested people are. I've been doing months of web searches but to no avail. However, I've found some "close-enoughs" that range from cheap to premium.

I've also found some ties that are Coulson-esque but don't directly correlate with screen-worn ties.

Anyone interested in comparing notes and research?
