EDIT: what vehicle had that kind of coolant bottle
91-93 Grand Prix's have that coolant bottle as stock equipment. The other W-body cars from those years may have that bottle as well, it's been a while since I've seen a 91-93 Cutty, Lumina, etc. engine bay though, so I could be mistaken.
A picture from my '93 SE w/ that coolant bottle...

Of course Matt's brand new bottle looks better than mine with 253,000 miles worth of heat and crap on it that have discolored it.
