Evening Reg!
It's an A-10 "Warthog".
Well... at least that's what google image search says... because I can't believe it's a cocktail glass...
Jokes aside, nice service this one, one more to add to the list that also includes TinEye, Gazopa and the like (usefeul with photos, definitely not with silhouettes though...).
Re the challenge (seriously), no idea, going to bed now, see you tomorrow afternoon.
