The one who was supposedly released with 7th ed. Dwarfs, but whose mold mysteriously broke? 
Weeeell, apparently it exists, somewhere in the deep crevasses of ebay:

Got no idea if itâs legit, or even real, or even GW but I remembered the whole mold-breaking-discussing on TWF and Warseer and this amused me 
Thorne:
I vaugely recall the model but after games workshop worked out the costings of such a sprue in relation to the loss of sales on metal figures they shelved the model mould after making several hundred first run samples. Those that remain are the first run samples.
Grimstonefire:
I am always amazed that people keep buying those. I know theyâre collectible as theyâre extremely rare, but the sprue/ models are really not good at all from what I can tell.
Iâve never actually seen anyone assemble and paint them.
Willmark:
Suprised essexgirl hasnât bought it yetâŚ
Pyro Stick:

I owned one myself till up about a year back and snapped some stills, their still up on Bugmans Brewery
here. The models aren't exceptional no (mind you, this is a 2006 sprue), but the sprue is still quite interesting.
Never dared cutting into the sprue though, seemed such a shame.
AGPO:
TBH, I wouldnât have bought that model on the grounds that tâs thoroughly uninspiring. Itâs basically just 2 plastic dwarf warriors with seperate cloaks. None of the components would make me think âthis is an epic hero of the dwarf race.â Youâd be better with Xanderâs tutorials and a touch of greenstuff.
