The second and third generation Standard Crowns can be seen in the Peto News forum.

You can see a second generation "Gasoline" Crown in the 8th picture. Oldgaser John O'hern has it for sale.
The first generation crowns are the ones with chimney caps. They have a style all their own. They also have "gasoline" etched around the base. Most of us will never see one of these in person.
