Cheyenne
The Cheyenne-class is one of the few ship designs with four warp nacelles.  The saucer hull is elliptical, but smaller than that of the Galaxy-class.
1.) The USS Ahwahnee NCC-73260 was one of the ships destroyed at Wolf 359, but could not be definitely identified in the graveyard scene, let alone the registry.  Anyway, a studio model with the above number is depicted in the Behind the Scenes Card Game.  There is a second Ahwahnee NCC-71620 that served in the tachyon web fleet in The Next Generation: "Redemption II".  It is not evident whether this is the same ship, salvaged after Wolf 359, or another ship that has been named in honor of the first one, for some strange reason with a lower, yet similar registry.
2.) According to the above card, the Cheyenne-class is a kitbashed design.  The saucer bottom from the small AMT/Ertl Enterprise-D kit including the neck is used as saucer top, and many windows have been either removed or extended to suggest a smaller ship.  The brige module is comparatively large and is obviously taken from the larger 1/1400 Enterprise-D.  The warp nacelles are actually highlighters!
